What is meant by magnetic force.Name amd explain the rule?
Answers
Motion of two electrically charged particles produce force of attraction or repulsion between them called ''Magnetic force''. The rule to determine direction of force experienced by a current carrying conductor in a magnetic field is called right hand rule in which one takes his right hand, curls his fingers and points his thumb in direction of current flowing through the wire, It creates a magnetic field around wire. Direction of curved fingers is the direction of magnetic field.
1) Doubling the magnitude of currents doubles the magnetic force as their is direct relation between these two.
2) Reversing the direction of current flow will reverse the direction of force.
3) Reversing the direction of magnetic field will again reverse the direction of displacement of force.
