Electromagnetic Induction - Quiz Quiz

Question 1

Which will produce a magnetic field?

Revolt · Accepted Answer

C: a wire carrying a current

Question 2

Which change will cause an increase in the electric current produced through electromagnetic induction?

Revolt · Accepted Answer

D: using more wire loops in the solenoid

Question 3

When the north pole of a bar magnet is moved into a solenoid, the needle on a galvanometer attached to the solenoid moves to the left, indicating that a current is produced. The magnet is then pulled out at a faster speed. What will be the result?

Revolt · Accepted Answer

D: a larger current in the opposite direction

Question 4

Which will produce a magnetic field?

Revolt · Accepted Answer
