Which of the following correctly describes the magnetic field near a long straight wire?
A current-carrying straight wire is held in exactly vertical position. If the current passes through this wire in the vertically upward direction, what is the direction of magnetic field produced by it? Name the rule used to find the direction of magnetic field.
When is the force experienced by a current-carrying conductor placed in a magnetic field largest?
A current flows in a wire running between the S and N poles of a magnet lying horizontally as shown in Figure below:
The force on the wire due to the magnet is directed:
fron N to S
from S to N
vertically downwards
vertically upwards
State under what conditions force acting on a current carrying conductor which is freely suspended in a magnetic field can be Zero.
The strength of magnetic field around a current-carrying conductor is ____________.
A magnetic field directed in north direction acts on an electron moving in east direction. The magnetic force on the electron will act ____________.
Which of the following pattern correctly describes the magnetic field around a long straight wire carrying current?
Assertion (A): A current carrying straight conductor experiences a force when placed perpendicular to the direction of magnetic field.
Reason (R): The net charge on a current carrying conductor is always zero.

The graph (fig A) illustrates the correlation between the number of protons (x-axis) and the number of neutrons (y-axis) for elements A, B, C, D, and E in the periodic table. These elements are denoted by the letters rather than their conventional symbols. When the element C, depicted in the graph, undergoes radioactive decay, it releases radioactive rays. When these rays are directed into the plane of the paper in the presence of a magnetic field, as indicated in the fig B, they experience deflection, causing them to move upwards.

Name the law used to identify the radioactive radiation emitted by the element.
