In an A.C. generator, when the plane of the armature is perpendicular to the magnetic field

Calculate the torque acting on a rectangular coil carrying current I placed in a uniform magnetic field when the plane of the coil is perpendicular to the magnetic lines of force.

What is the direction of magnetic force when velocity of charge is perpendicular to the magnetic field.

A ring is rotated about diametric axis in a uniform magnetic field perpendicular to the plane of the ring. If initially the plane of the ring is perpendicular to the magnetic field. Find the instant of time at which EMF will be maximum & minimum respectively. (Figure: )

When a charged particle moves perpendicular to a magnetic field, then

When a charged particle moves perpendicular to a magnetic field, then:

Assertion A charged particle is rotating in a circular path in uniform magnetic field. Then, plane of circle is perpendicular to the magnetic field. Reason Circular motion is a two-dimensional motion.
