Question

geometrical length of magnet is 54 m then what should be its magnetic length​

Answer 1

Answer:

The answer will be 45 m

Explanation:

According to the problem the geometrical length of the magnet is given as 54 m

Now we know that  Magnetic length can be calculated by the formula of the  five by six of the geometrical length

Therefore for this case

The magnetic length will be M = five / six of G= 5/6 * 54= 45 m [ where G is the geometric length]
