An electron does not suffer any deflecton while passing through a region of uiform magnetic field. What is direction of the magnetic field ?

Explanation

When an electron enter in a region of uniform magnetic field force experienced by charge particle `vec F = ( vec v xx vecB)` an electron does nt suffer by any deflection while passing parallel to magnetic field because in this case ` theta = 0^(@)`
`F = q v B sin theta ^(@) = 0`
