Frank,
That magnetic flux intensity, micro Tesla, is very low.
Likely would have no harmful effects, unless you sleep on top of the line every day.
It would be instructive to google magnetic flux intensity in the work place, such a a plane cockpit, etc.
PLAYING RUSSIAN ROULETTE WITH RELIABLE ELECTRICITY SERVICE IN NEW ENGLAND
https://www.windtaskforce.org/profiles/blogs/playing-russian-roulet...
New England experienced an unusual cold spell from December 24, 2017 – January 8, 2018
The image was created by the New England electric system operator, ISO-NE.
Offshore Wind Systems
Denmark
installed the first offshore wind system in 1983; Germany, the Netherlands, the UK, etc., followed.
National grids were connected with high-voltage DC lines. Electricity is distributed/curtailed, during high winds, as needed.
European companies have installed more than 25,000 MW of offshore wind systems (the US has 35 MW) during the past 40 years, about 1,000 MW/y during recent years.
Massachusetts, Connecticut
It took several years for Massachusetts and Connecticut to sign contracts with EU/US wind consortia for about 1,000 MW of NE offshore wind systems
Almost all of the NE offshore wind systems would be supplied and installed by European companies, during the next 20 years.

Maine
Maine RE folks have a goal to install hundreds of 12 MW, 850-ft-high, offshore FLOATING wind turbines.
However, that approach would be much more expensive per MW, than normal offshore wind systems, and would require major extension/augmentation of the NE grid.
At present, there are no major wind companies with any experience, other than minor experience by Norway having a demonstration system off the coast of Scotland.

Exorbitant “All-in” Electricity Cost of Wind and Solar in New England
https://www.windtaskforce.org/profiles/blogs/high-costs-of-wind-sol...
http://www.windtaskforce.org/profiles/blogs/cost-shifting-is-the-na...
Pro RE folks always point to the “price paid to owner” as the cost of wind and solar, purposely ignoring the other cost categories. The all-in cost of wind and solar, c/kWh, includes:
1) Above-market-price paid to Owners
2) Subsidies paid to Owners
3) Owner return on invested capital at about 9%/y
4) Grid extension/augmentation
5) Grid support services
6) Future battery systems
Comments on table 5
- Vermont legacy SO solar systems had greater subsidies, up to 30 c/kWh paid to owner, than newer systems, about 11 c/kWh
- Wind prices paid to owner did not have the drastic reductions as solar prices.
- Vermont utilities are paid about 3.5 c/kWh for various costs they incur regarding net-metered solar systems
- "Added to the rate base" is the cost wind and solar are added to the utility rate base, used to set electric rates.
- “Total cost”, including subsidies to owner and grid support, is the cost at which wind/solar are added to the utility rate base
- “NE utility cost” is the annual average cost of purchased electricity, about 6 c/kWh, plus NE grid operator charges, about 1.6 c/kWh
for a total of 7.6 c/kWh.
- “Grid support costs” would increase with increased use of battery systems to counteract the variability and intermittency of increased build-outs of wind and solar systems.
NOTES:
1) NE wholesale grid price averaged about 5 c/kWh or less, starting in 2009, due to low-cost CCGT and nuclear plants providing at least 65% of all electricity loaded onto the NE grid, in 2019.
- Wind, solar, landfill gas, and methane power plants provided about 4.8%
- Pre-existing refuse and wood power plants provided about 4.6%
- Pre-existing hydro power plants provided about 7.4%
- The rest was mostly hydro imports from the very-low-CO2 Canada grid, and from the much-higher-CO2 New York State grid

2) There are Owning costs, and Operating and Maintenance costs, of the NE grid
ISO-NE charges these costs to utilities at about 1.6 c/kWh.
3) ISO-NE charges are for:
Regional network services, RNS, based on the utility peak demand occurring during a month
Forward capacity market, FCM, based on the utility peak demand occurring during a year.

Sample calculation; NE utility cost = 6, Purchased + 1.6, (RNS + FCM) = 7.6 c/kWh
Sample calculation; added to utility base = 17.4 + 3.5 = 20.9 c/kWh
Sample calculation; total cost = 17.4 + 5.2 + 2.1 + 3.5 + 1.6 = 29.8 c/kWh
Excludes costs for very expensive battery systems
Excludes costs for very expensive floating, offshore wind systems
Excludes cost for dealing with shortfalls during multi-day wind/solar lulls. See URL

“Added to rate base” is for recent 20-y electricity supply contracts awarded by competitive bidding in NE.
“Added to rate base” would be much higher without subsidies and cost shifting.
Areas with better wind and solar conditions, and lower construction costs/MW have lower c/MWh, than NE

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT
******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********
(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?
We have the facts on our side. We have the truth on our side. All we need now is YOU.
