Can we have a single north pole, or a single south pole?

Assertion (A): It is not necessary that every magnet has one north pole and one south pole. Reason (R ): It is a basic fact that magnetic poles occur in pairs

Chordates have single or paired gill slits

How do you find the north pole and south pole of a magnet?

Compare the direction of the magnetic field inside a solenoid with that of the field there if the solenoid is replaced by its equivalent combination of north pole and south pole.

In the given figure, the north pole of a magnet is brought towards a closed loop containing a condenser. Positive charge will be produced on

Poles of a magnet

A single photon excites only a single electron

A: Every magnetic configuration magnetic field north pole and south pole. R: North pole, south pole exists only if the source of the field has net magnetic dipole moment.

A bar magnet 30cm long is placed in magnetic meridian with its north pole pointing south. The neutral point is observed at a distance of 30cm from its centre. Calculate the pole strength of the magnet. Given horizontal component of earth's field is 0*34G .

Does a single particle of a gas have temperature?
