A magnet always has __________ poles

The product of pole strength and the magnetic length of a magnetic is called __________

The north pole of a magnet__________the north pole of another magnet.

The strength of a magnetic pole is measured in terms of pole strength. Pole strength depends on number of free poles exposed at the end of the magnet. Number of free poles exposed at the end of magnet inturn depends on the area of cross section of the magnet. A bar magnet has a pole strength 'K'. If is cut into 2007 parts as shown in the figure. The pole strength of each piece now is ____

The earth's magnetic field always has a vertical component except at the

Earth's magnetic field always has a horizontal component except at

Earth's magnetic field always has a horizontal component expert at or Horizontal component of earth's magnetic field remains zero at

The north pole of a magnet________the north pole of another magnet.

Statement-1 A freely suspended bar magnet always comes to lie in North-South direction. Statement-2 Magnetic poles have the property of directionality

(a) Define magnetic field lines. Describe an activity to draw a magnetic field line outside a bar magnet from one pole to another pole. (b) Explain why, a freely suspended magnet always points in the north-south direction.
