`P` and `Q` are two unlike magnetic poles. Induction due to `'P'` at the location of `'Q'` is `B`, and induction due to `'Q'` at the location of `P` is `B//2`. The ration of strength of `P` and `Q` is

Two solenoids acting as short bar magnets P and Q are arranged such that their centres are on the X-axis and are separated by a large distance. The magnetic axes of P and Q are along X and Y-axes, respectively. At a point R, midway between their centres, if B is the magnitude of induction due to Q , then the magnitude of total induction at R due to the magnitude is

Magnetic induction at a point P on the axis is 54 times the magnetic induction at a point Q on the equator of a short magnetic dipole. The ratio of the distances of the points P and Q from the dipole is given by
