Shady was introducing his invention to a “Birds Unlimited” convention. He explained that he developed a special insulation for high-powered electrical lines. This insulation is guaranteed to save thousands of birds that unwittingly land on the lines and are electrocuted each year. Shady claimed that with all the birds saved, the annual summer mosquito problem would practically disappear. As Shady was appealing for donations, Captain Frank, an avid bird lover, stood up and told Shady to peddle his line elsewhere. What was wrong with Shady’s claim?
Answer
High-powered electrical lines have such a strong magnetic field that it is virtually impossible for birds to land on them. The magnetic field will actually repel the birds.
