Question

1. Which acts like a magnet?
A. nail
B. wire
C. dry cell
D. none of the above

2. What is produced when electricity flows in a conductor?
A.coil
B.magnetism
C. nail
D. wire​

Answer 1

The answer to the given question is given below:

1. The correct answer to the given question is option A: Nail and option B: Wire under below specified conditions only.

• When natural powerful magnets are used to generate magnetic characteristics in a nail composed of iron, the nail becomes a magnet.
• However, it only acts as a magnet for a short period of time.
• Only when the circuit is closed and switched on with current or electricity flowing across it can a wire behaves or operate as a magnet.
• Wire does not operate as a magnet if no charges flow.
• Hence, both act as magnets under the conditions mentioned above.

2. The correct answer to the question is option B: Magnetism.

• We can respond to this answer using electromagnetic effects of conductors notions.
• Because of the changing velocity rates of charged particles, every conductor with electricity flowing creates magnetism properties.
• As a result, the charge's movement creates magnetic effects.
