In a certain arrangement, a proton does not get deflected while passing through a magnetic field region.Under what condition is it possible?

The wire does not breaks the ice slab while passing through it.Why?

An electron is not deflected in passing through a certain region of space. Can we be sure that there is no magnetic field in that region?

An electron and proton moving with same speed enter the same magnetic field region at right angles to the direction of the field.For which of the two particles will the radius of circular path be smaller ?

A uniform magnetic field of 1.5 T exists in a cylindrical region of radius 10.0 cm, its direction parallel to the axis along east to west. A wire carrying current of 7.0 A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire. If, the wire intersects the axis .
