Moving Charges ...

The force felt by an electron on entering into a magnetic field is independent of its

You are sitting in a room in which uniform magnetic field is present in vertically downward direction. When an electron is projected in horizontal direction, it will be moving in circular path with constant speed

A neutron , a proton, an electron and an $$\alpha $$ particle enter  perpendicular uniform magnetic field, with the same uniform velocity. The path of electron in the following figure will be :

The magnetic field  $$\overline{dB}$$ due to a small current element dl at a distance $$\vec{r}$$ and carrying current ‘i’ is

For a given distance from a current element, the magnetic induction is maximum at an angle measured with respect to axis of the current. The angle is :

A positive charged particle enters at the middle as shown in the figure with $$10^{5}\ m/s$$ will bend:

A magnetic field exerts no force on

Magnetic field at a point on the line of current carrying conductor is

If the direction of the initial velocity of the charged particle is perpendicular to the magnetic field, the orbit will be :

A cathode ray beam is bent into an arc of a circle of radius $$0.02 m$$ by a field of magnetic induction $$4.55 mT$$. The velocity of electrons is:
(Given $$e=1.6\times 10^{-19}c$$ and $$m=9.1\times 10^{-31}kg$$)
