2) Magnets are made up of different materials and different shapes.

3) There is a maximum attraction in middle of a magnet.​

Answer 1

3)There is a maximum attraction in middle of a magnet.is false

the magnetic field lines near the center are parallel to the length of the bar. Moreover, the density of the field lines is maximized at the "poles" of the bar magnet and minimized at the center which means that the magnitude of the magnetic field is smallest at the center.The strength of the poles is maximum at the ends of the magnet. A freely suspended magnet always aligns itself in North-South direction. Always the needle of the compass points towards North-South direction. So if North-South direction is known then East-West direction can also be known.
