CBSE | Poles and directions of magnet

If a traveller using a compass needle follows the direction of the magnetic needle, would be able to reach the geographic north pole ? Explain in detail.

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.

(a) Describe an activity to show with the help of a compass that magnetic field is strongest near poles of a bar magnet. (b) Mention the direction of magnetic field lines (i) inside a bar magnet and (ii) ouside a bar magnet.

A wire is placed between the poles of twofixed bar magnets as shown in the figure. A small current in the wire is into the plane of the paper. The direction of the magnetic force on the wire is

when the wire loop is rotated in the magnetic field between the poles of a magnet the direction of emf changes once in every
