(b) SI unit of Magnetic field?
(c) What is the direction of magnetic field lines outside a bar magnet?
Q2- What is magnetic field? Why does a compass needle show deflection when brought near the bar magnet?
Q3-State the properties of magnet.
Q4- What are magnetic field lines of force?State the characteristics of those lines.
Q5-Draw the magnetic field lines pattern around a bar magnet.
Q6-Represent uniform magnetic field with the help of a diagram.
Q7-Name an instrument in which directive property of magnets is used.
Q8-Explain ,why two magnetic field lines never intersect?
Q9-What are the two ways in which you can trace the magnetic field pattern of a bar magnet?
Q10-Explain why, a freely suspended magnet always points in the north-south direction.
A10-A freely suspended magnet points in the north-south direction because earth behaves as a magnet with its south pole in the geographical north and the north pole in the geographical south.​

Answer 1

Answer:

1) due to attraction of poles.

2)SI unit of magnetic field is Tesla.

3) They can never cross the field at any point in space. Magnetic field lines are continuous. They go from the north pole to the south pole.

4) A magnetic field lines is an imaginary curve along which a free unit north pole tends to move.

7)compass
