If an electron is moving with velocity v produces a magnetic field B, then
(a) the direction of field will be same as the direction of velocity
(b) the direction of field B will be opposite to the direction of velocity V.
(c) the direction of field B will be perpendicular to the direction of velocity v
(d) the direction of field B does not depend upon the direction of velocity

If an electron is moving with velocity v produces a magnetic field vecB , then

The direction of the field B at P is

A particle having a mass of 10^(-2) kg carries a charge of 5 xx 10^(-8) C . The particle is given an initial horizontal velocity of 10^(5) msec^(-1) in the presence of electric field vec(E) and magnetic field vec(B) . To keep the particle moving in a horizontal direction, it is necessary that A. vec(B) should be perpendicular to the direction of velocity and vec(E) should be along the direction of velocity B. Both vec(B) and vec(E) should be along the direction of velocity C. Both vec(B) and vec(E) are mutually perpendicular and perpendicular to the direction of velocity D. vec(B) should be along the direction of velocity and vec(E) should be perpendicular to the direction of velocity

The direction of the field B at P is the V shaped wire is in x-y plane

An electron moving towards the east enters a magnetic field directed towards the north. The force on the electron will be directed

Direction of Magnetic Field

An electron is travelling along the x-direction. It encounters a magnetic field in the y-direction. Its subsequent motion wil be

If an electron enters a magnetic field with its velocity pointing in the same direction as the magnetic field, then

A rod when suspended in a magnetic field stays in east-west direction. Can we be sure that the field is in the east-west direction? Can it be in the north-south direction?
