State important characteristics of magnetic force experienced by charge
moving in a magnetic field (or a current-carrying conductor placed in a magnetic
field).
[CBSE 2014]
Answers
Answer:
We know that a current passing through a conductor produces a magnetic field. The field so produced exerts a force on the magnet placed at the vicinity of the conductor. French scientist Andre Marie Ampere suggested that the magnet must also exert an equal and opposite force on the current carrying conductor. We can find the direction of the force acting on the conductor using Fleming's left-hand rule.
Explanation:
Answer:
A magnetic force experienced around the region of a magnet is called magnetic field. The characteristics of magnetic field lines are as follows:
(i) The magnetic field lines of a magnet start from the North Pole(N) and reach the South Pole(S) and these lines are in the north-south direction inside the magnet.
(ii) The region in which the field lines are at close distance to each other has a strong magnetic field and if the field lines are at far distance from each other, the region has a weak magnetic field. Near the poles of a magnet, the field lines are at close distance from each other so there is strong magnetic field.
(iii) The magnetic field is a very vector quantity. So it has magnitude and direction both. The tangent is drawn at any point of a magnetic field line.
(iv) Magnetic field lines do not intersect each other.
