Question

Suppose a wire of length 10m and Mass 50g is suspended in air in a region with magnetic field of 0.5 T at right angle to the wire.if the angle with which the magnetic field makes with the wire is less than right angles (90°). What will happen to the wire?

When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the current. This force is given by the equation F = I * L * B * sinθ, where F is the force, I is the current, L is the length of the wire, B is the magnetic field strength, and θ is the angle between the wire and the magnetic field.

In this case, the wire is suspended in air, so the current is zero. However, if the wire is moved or if an external source of current is connected to it, a current will flow through the wire due to the presence of the magnetic field.

If the angle θ is less than 90 degrees (i.e., the wire makes an acute angle with the magnetic field), the force exerted on the wire will be perpendicular to both the current and the magnetic field. This force will cause the wire to move in a direction perpendicular to both the current and the magnetic field.

Therefore, if the wire is allowed to move freely, it will experience a net force and will be pushed in a direction perpendicular to both the current flowing through it and the magnetic field.
