Question

which is best suited for making magnetic keepers
a. Iron
b. Wood​

Answer 1

Answer⇲

➤ Steel and Iron are suitable for making a magnetic keeper as they have low enough coercivity and susceptibility. Iron is preferred to steel as Iron gets magnetized easily and completes the circuit and does not retain any field when it is reattached to the permanent magnet. Therefore the correct option is B.

Answer 2

Question:-

Which is best suited for making magnetic keepers

a. Iron

b. Wood

_________

Answer:-

a. Iron

_____________________________

Reason:-

Two magnets attract to each other because their fields interact.

A magnet is not attracted to a piece of wood because no internal field in induced in the wood. With no induced internal field in the wood, there is no field interaction and no attraction.

So, a magnetic field can be induced in a piece of steel.
