Question

The figure shows a bar magnet brought near the piece of steel.if so

• A. A gets North polarity and B gets South polarity
• B. A gets North polarity and B gets no polarity
• C. A gets South polarity and B gets North polarity
• D. A gets South polarity and B gets no polarity

Answer 1

Answer:

C. A gets South polarity and B gets North polarity

• A piece of steel is brought near a permanent magnet, it becomes magnetized via magnetic induction.

• The magnetic field of the permanent magnet lines up the atomic magnetic domains inside the steel.

• In magnetic induction, the near end always develops an opposite polarity to attract the inducing pole, while the farther end develops the same polarity.

• Since the North pole (N) of the bar magnet is facing end A, end A develops a South polarity, and end B develops a North polarity.
