Question

When a magnet is heated, then it -

• A. Either option $\left(A\right)$ or $\left(B\right)$
• B. loses its entire magnetic property.
• C. becomes a stronger magnet.
• D. becomes a weaker magnet.

Answer 1

The correct option is A Either option $\left(A\right)$ or $\left(B\right)$

When a magnet is heated, it begins to lose its magnetic properties, $i.e.$, it goes on becoming weaker and weaker with increasing temperature.

At a certain temperature, it loses its entire magnetic properties.

As temperature is not mentioned, hence, option $\left(D\right)$ will be the correct answer.
