Electromagnetic Induction — Quiz

Question 1

Which will produce a magnetic field?

Revolt · Accepted Answer

a wire carrying a current

Question 2

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

Revolt · Accepted Answer

using more wire loops in the solenoid

Question 3

Which will produce a magnetic field?

Revolt · Accepted Answer

a wire carrying a current

Question 4

Tonya is modeling the discovery of electromagnetic induction. Which procedure should she use?

Revolt · Accepted Answer

moving a magnet into a coil of wire in a closed circuit

Question 5

An electric current is produced using a bar magnet and a solenoid. Which changes will cause a decrease in the electric current produced? Choose two correct answers.

Revolt · Accepted Answer

using fewer wire loops in the solenoid; moving the magnet more slowly

Question 6

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

a larger current in the opposite direction

Question 7

Which changes will cause an increase in the magnetic field of a solenoid? Choose three correct answers.

Revolt · Accepted Answer

decreasing the spacing between loops; using more wire loops; using a larger current

Question 8

Which describes Michael Faraday’s work with electricity and magnetism?

Revolt · Accepted Answer

He discovered electromagnetic induction after seeing a changing magnetic field generate an electric current.; He discovered electromagnetic induction after seeing a compass needle deflected by a flowing electric current.

Question 9

Which change would reverse the direction of the electric current generated through electromagnetic induction?

Revolt · Accepted Answer

using the opposite pole of the magnet

Question 10

Julia produces a 2 mA current by moving the south pole of a bar magnet into a solenoid. The solenoid contains 150 loops of wire. Which change should Julia make to generate a larger current?

Revolt · Accepted Answer

using more loops of wire in the coil
