Magnetic Properties Quiz

Which of the following objects can exhibit magnetic properties?

• Plastic cups

• Wooden chairs

• Refrigerator doors

• Paper sheets

Every magnet has which of the following?

• One pole

• Two poles

• Three poles

• No poles

Where is the magnetic effect strongest in a magnet?

• The center

• The edges

• The poles

• Everywhere equally

Magnetic fields are represented by:

• Electric field lines

• Magnetic field lines

• Gravitational field lines

• Light rays

Magnetic field lines:

• Can cross each other

• Are discontinuous

• Form closed loops

• Start from the south pole

The number of magnetic field lines passing through a unit area is called:

• Magnetic force

• Magnetic flux

• Magnetic intensity

• Magnetic potential

The SI unit for magnetic field is:

• Weber (Wb)

• Ampere (A)

• Tesla (T)

• Volt (V)

The SI unit for magnetic flux is:

• Tesla (T)

• Weber (Wb)

• Newton (N)

• Joule (J)

The force on a charge moving in a magnetic field is proportional to:

• The charge only

• The velocity only

• The magnetic field only

• All of the above (charge, velocity, and magnetic field)

The direction of the magnetic force is:

• Parallel to the magnetic field

• Parallel to the velocity

• Perpendicular to both the velocity and the magnetic field

• In the same direction as the velocity
