Electricity is used to pump water up to a reservoir. Compressed air. Electricity is used to compress air at up to 1,000 pounds per square […]

What does a changing magnetic field causes? A changing magnetic field induces a current in a conductor. For example, if we move a bar magnet near a conductor loop, a current gets induced in it. The E.M.F. E induced in a conducting loop is equal to the rate at which flux ϕ through the loop […]
