Expert Answer:
The earth's magnetic field is from south to north. To neutralise the earth's magnetic field, the field generated by the current carrying conductor must be equal and opposite to that of the earths magnetic field. now the current is going vertically downwards in the wire, so the direction of magnetic field as seen from the top of the wire is in anticlockwise direction.

- As we know, work done by Magnetic force is always zero in moving a charged particle./So it cannot change speed of charged particle. MY doubt is that, can magnetic force change direction of motion of charged particle?
- Sir , if a magnetic field is increasing in a cylindrical volume at a constant rate. then what will be direction of instantaneous acceleration experienced by an electron placed inside cylinder but not on center?
- Hii
- What do you mean by magnetic Lorentz force?
- When will be the force experienced by moving charge in a magnetic field maximum and minimum?
- What is the work done by a magnetic field on a moving charge?
- In the expression, F= qvBsinθ which pair of vectors among
,
and
is always perpendicular to each other.
- Deduce an expression for the force experienced by the moving charged particle in a uniform magnetic field?
- State the rule, which governs the direction of the magnetic Lorentz force.
