Magnetism and Electricity

What happens when like poles of two magnets are brought together?

• They attract each other.

• They repel each other.

• They create a magnetic field.

• They become neutral.

What happens when opposite poles of two magnets are brought together?

• They repel each other.

• They attract each other.

• They have no effect on each other.

• They create a magnetic field.

What is static electricity?

• Static electricity is the accumulation of electric charge on the surface of objects.

• Static electricity is the flow of electric charge through a conductor.

• Static electricity is the energy produced by moving electrons in a circuit.

• Static electricity is the force that attracts magnets to metal.

What is the role of electric charges in magnetism?

• Electric charges have no effect on magnetism.

• Moving electric charges create magnetic fields.

• Static electric charges repel magnetic fields.

• Electric charges can only exist in magnetic fields.

What is the relationship between electricity and magnetism?

• Electric currents produce magnetic fields, and changing magnetic fields can induce electric currents.

• Electricity and magnetism are completely independent phenomena.

• Magnetism can only exist in the absence of electricity.

• Electricity is a form of magnetism that can be harnessed for power.

What materials are typically attracted to magnets?

• Copper, Zinc, and Silver

• Iron, Nickel, and Cobalt

• Aluminum, Gold, and Platinum

What is magnetism?

• A force that can attract or repel certain materials, primarily metals like iron, nickel, and cobalt.

• A type of energy that can only attract materials.

• A phenomenon that occurs only in electric fields.

• A force that affects all materials equally.
