An electric current is produced using a bar magnet and a solenoid. which changes will cause a decrease in the electric current produced? check all that apply. using more wire loops in the solenoid using fewer wire loops in the solenoid using a stronger magnet moving the solenoid instead of the magnet moving the magnet more slowly

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
