Question 1

Which of the following statements best describes the origin of the term 'magnetism'?

Accepted Answer

It is named after the Greek city of Magnesia, where natural magnets were found.

Question 2

Which scientist first demonstrated that an electric current creates a magnetic field?

Accepted Answer

Hans Christian Oersted

Question 3

A bar magnet is cut in half. What happens to the magnetic poles of the resulting pieces?

Accepted Answer

Each piece will have both a north and a south pole.

Question 4

Which of the following is NOT a property of magnetic field lines?

Accepted Answer

They cross each other at strong magnetic regions.

Question 5

Which of the following best explains why the Earth’s geographic north pole is actually a magnetic south pole?

Accepted Answer

Because magnetic field lines enter the geographic north pole.

Question 6

Which of the following is the correct SI unit for magnetic field strength?

Accepted Answer

Tesla

Question 7

A current-carrying wire produces a magnetic field. What is the shape of the magnetic field lines around the wire?

Accepted Answer

Concentric circles centered on the wire

Question 8

Which of the following scenarios will NOT induce an electric current in a conductor?

Accepted Answer

A stationary magnet near a stationary conductor

Question 9

Which of the following factors does NOT affect the magnitude of the induced voltage in electromagnetic induction?

Accepted Answer

The temperature of the conductor

Question 10

Which of the following statements about magnetic domains is correct?

Accepted Answer

Domains are regions where the magnetic fields of individual atoms are aligned.

Question 11

Which of the following is a correct statement about the force on a charged particle moving in a magnetic field?

Accepted Answer

The force is always perpendicular to both the velocity and the magnetic field.

Question 12

Which of the following best describes the relationship between electricity and magnetism as discovered by Faraday and Oersted?

Accepted Answer

A changing electric field can produce a magnetic field, and a changing magnetic field can produce an electric field.

Question 13

Which of the following is a real-world application of electromagnetic induction?

Accepted Answer

The generation of electricity in power plants

Question 14

Which of the following statements about magnetic monopoles is correct?

Accepted Answer

No magnetic monopole has ever been detected.

Question 15

Which of the following best explains why a coil of wire with an electric current becomes an electromagnet?

Accepted Answer

The moving charges in the wire produce a magnetic field.

Question 16

A wire carrying a current is placed in a magnetic field. Which of the following will increase the force on the wire?

Accepted Answer

Increasing the strength of the magnetic field

Question 17

Which of the following is the best analogy for the source of magnetism in a material?

Accepted Answer

Most electrons spinning on their axes in the same direction

Question 18

Which of the following is NOT a correct statement about the properties of magnets?

Accepted Answer

Like poles attract, unlike poles repel.

Question 19

Which of the following is a consequence of the Earth's magnetic field periodically reversing?

Accepted Answer

Deposits of magnetized material show alternating directions of magnetization.

Question 20

Which of the following best describes light according to the modern view of electromagnetic induction?

Accepted Answer

Light is a self-inducing electric and magnetic field carrying energy through space.
