SUBN

Answer 1

Answer:D

Step-by-step explanation:

Answer 2

D. it demonstrates electromagnetism.

Step-by-step explanation:

If a wire carrying current causes the needle of a compass to move, it is an example of electromagnetism.

The interaction between electric and magnetic fields is termed electromagnetism.

• Electromagnetic interaction is usually induced between a wire and bar magnet.
• With right set up magnetic and electrical fields can be induced using a magnet and current carrying wire.
