Question

Define si unit of magnetic field. under what condition does a moving charge experience: a.maximum force b.minimum force

Answer 1

Tesla is the unit. it is defined as a particle carrying a charge of 1 coulomb and passing through a magnetic field of strength 1 Tesla at a speed of 1 m/s perpendicular to said field and experiencing a force with a magnitude 1 newton.

Maximum force is experienced when force is moving perpendicular to magnetic field. Minimum force is experienced when force is moving parallel to magnetic field.

Answer 2

The Si unit of magnetic field is tesla

Maxmium force- when the velocity of charge and the magnetic field are perpendicular to each other

Minimum force- when this charge is moving in the direction of the magnetic field
