Student Notes U5 D4 slide deck- Electromagnets

Multiple Choice

Which of the following best describes the relationship between electricity and magnetism?

• Electricity and magnetism are completely unrelated phenomena.

• Electricity can create magnetic fields, and changing magnetic fields can create electric currents.

• Magnetism only exists in permanent magnets and has nothing to do with electricity.

• Electricity and magnetism only interact in batteries.

Multiple Choice

How are changing electric fields and magnetic fields related according to the introduction to Unit 5 Phenomena?

• Changing electric fields create magnetic fields, and changing magnetic fields can cause electrical charge to move.

• Changing electric fields have no effect on magnetic fields.

• Magnetic fields only exist in the absence of electric fields.

• Electric fields and magnetic fields are completely independent.
