What will happen if an electric current is flowing through a cord and a magnet is brought near the cord?

The choices are

The resistance of the wire will decrease

It will exert a force on the voltage

It will exert a force on the electric current

The electric current will stop flowing

The magnet will exert a force on the electric current

Explanation:

The electric current flowing through the cord will experience magnetic force due to presence of magnetic field created by the magnet brought near it.

The magnitude of the magnetic force experienced by this flowing current is given as;

F = qvB

where;

q is charge of electron (measured in coulomb's, C)

v is the speed of the flowing current (m/s)

B is the magnetic field strength (T)

Therefore, the magnet will exert a force on the electric current

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
