Fig. 13.5

(i) Which of the iron bar is likely to be the strongest magnet? 

(ii) Which of the iron bars is not a magnet? Justify your answer. 

Show solutionHide solution
Worked solution

Ans: i) Among the four given magnets, the Iron bar marked with (a) is the strongest magnet since many filings are attached to it.


ii) The Iron bar that has no filings attached to it is not a magnet. Such a piece is an Iron bar (b).


Q11Written answer

A toy car has a bar magnet laid hidden inside its body along its length. Using another magnet, how will you find out which pole of the magnet is facing the front of the car? 

Show solutionHide solution
Worked solution

Ans: We'll take a bar magnet and point the north pole towards the car, then the south pole is at the front of the car if the automobile is attracted to it. If it is rejected, it indicates that the North Pole is in front of the vehicle. The magnet's attraction and repulsion cause this phenomenon. Poles that are similar repel each other, whereas poles that opposite attracts each other.

Q13Written answer

You are provided with two identical metal bars. One out of the two is a magnet. Suggest two ways to identify the magnet. 

Show solutionHide solution
Worked solution

Ans: There are two techniques to recognise magnets.

  1. Take both metal bars and place them in the iron filings, then remove them immediately. The magnet will be filled with iron filings, while the regular metal bar will have no filings.

  2. Place a magnet near each of the metal bars one at a time. The magnetic bar that attracts or repels the magnet is magnetic, whilst the other is not.
