Properties of Bar Magnet

What happens when we cut a magnet diagonally?

What happens to the magnetic dipole moment of a bar magnet if it is cut into two pieces along its length?

What happens when a magnet is cut in half?

What happens when a magnet is cut in half?

Calculate the geometric length of a bar magnet of pole strength $80 \mathrm{Am}$ and magnetic moment $4{\mathrm{Am}}^2$
 

What is the ratio between the magnetic length and the geometric length?

What is geometric and magnetic length.

Magnetic poles exist in _____.

A bar magnet having a magnetic moment $\overrightarrow{M}$ is cut into four pieces i.e., first cut in two equal pieces along the axis of the magnet and each piece is further cut into two equal pieces along the axis. Compute the magnetic moment of each piece.

The magnetic moment of a bar magnet is $3.6\times {10}^{-3}\mathrm{ }\mathrm{A} {\mathrm{m}}^2$. Its pole strength is $120 \mathrm{mA} \mathrm{m}$. Its magnetic length is

The areas of cross-sections of three magnets of same length are $A, 2A$ and $6A$ respectively. The ratio of their magnetic moments will be

When a bar magnet is broke into different pieces, each piece is a complete magnet.

Why we get two null points for a bar magnet? Can we get only one null point? How?

Write unit of pole strength.

Which field is produced by a moving charge.

The pole strength of a horse shoe magnet is $90 \mathrm{A} \mathrm{m}$ and distance between the poles is $6 \mathrm{cm}$. The magnetic induction at mid point of the line joining the poles is,

$P$ and $Q$ are two unlike magnetic poles. Induction due to $\text{'}P\text{'}$ at the location of $\text{'}Q\text{'}$ is $B$, and induction due to $\text{'}Q\text{'}$ at the location of $P$ is $\frac{B}{2}$. The ratio of pole strengths of $P$ and $Q$ is

The magnetic induction at distance of $0.1 \mathrm{m}$ from a strong magnetic pole of strength $1200 \mathrm{A}\hspace{0.17em}\mathrm{m}$ is

The geometric length of a bar magnet is $24 \mathrm{cm}$. The length of the magnet is

Assertion: Poles of a magnet can never be separated.

Reason: Since each atom of a magnetic material is a magnet in itself.
