Two magnets are shown in figure.
Choose the correct statement regarding the pole strength of the two magnets.
ABoth X and Y have same pole strength.
BPole strength of X is greater than that of Y.
CPole strength of Y is greater than that of X.
DData insufficient.
Got confused as material also affects strength and material is not specified but answer is b
Ans 1:
Class : Class 8
The correct answer is B, as the more the length of the attracting material stronger the magnetic field
Ans 2:
Class : Class 2
As they did not give the material of which magnet were made, how can be sure that magnet X has a stronger force than magnet Y? After all, the material of the magnet is also an important factor to determine the strength.
Ans 4:
Class : Class 7
Isn't there insufficient data? We don't know much about the magnet, what if the thinner magnet has greater micro Tesla than the thicker magnet? It would result in Y being thicker than X. We cannot assume such information such as other factors and materials are equal without a little background about it.
