Questions Related to field due to a current carrying conductor
Biot-Savart law indicates that the moving electrons (velocity $\bar v$ ) produce a magnetic field $\bar B$ such that:
A particle of charge per unit mass $\alpha$ is released from origin with a velocity $\mathop v\limits^ \to = {v _0}\mathop i\limits^ \wedge $ in a uniform magnetic field $\mathop B\limits^ \to = - {B _0}\mathop k\limits^ \wedge $ . If the particle passes through (0,y,0) then y is
equal to
A vertical straight conductor carries a current vertically upwards. A point P lies to the east of it at a small distance and another point Q lies to the west at the same distance the magnetic field at P is :
If a current carrying wire carries 10A current then the magnetic field is X. Now the current in the wire increases to 100A, them magnetic field in the wire becomes
The magnetic field produced by a current-carrying wire at a given point depends on
If magnetic field produced by a straight current carrying wire at a distance 10cm from it is X. Then the magnetic field produced at a distance 29cm will be
Which of the following relation represents Biot-Savart's law?
A long cylindrical wire of radius R carries a current $i$ distributed uniformly over its cross section.Find the maximum magnetic field produced by this wire.
Motion of charges is noting but :
A condenser is charged using a constant current. The ratio of the magnetic field at a distance of R/2 and R from the axis is (R the radius of plate)
