Question

A compass needle normally points toward Earth’s magnetic pole, which is near the North Pole. Which best explains why the needle moves away from the pole when it comes close to a current-carrying wire?

Current within the wire weakens the magnetic force of the pole.
Magnetism surrounding the wire weakens the magnetic force of the pole.
Current within the wire draws the needle toward the wire.
Magnetism surrounding the wire draws the needle toward the wire.

Answer 1

Explanation:

Some permanent magnets are made with alnico—an alloy of aluminum, nickel, cobalt, and iron

Answer 2

Answer:

The correct answer is Option D

Magnetism surrounding the wire draws the needle toward the wire.

Explanation:

• When a compass needle normally points toward Earth's magnetic pole, the best way to explain why the needle moves away from the pole when it comes close to a current-carrying wire is Magnetism surrounding the wire draws the needle toward the wire.
• Due to the presence of Electric charge the magnetic field is generated.
• The force magnetism operation is based on the magnetic field in the area around the electric charge.
• The compass points towards the north direction because all the magnets have two pole they are North pole and the South pole in which the North pole attracts the south pole and the south pole attracts the north pole.
• The Earth is the magnet which attracts with other magnets so the North end of the compass was aligned to the Magnetic field of the Earth.
• When the needle comes close to the current - carrying wire the current is increased and it causes the deflection of the needle so the needle moves away from the pole
