Detailed Solution

The quantity of force imposed on a current-carrying conductor in a magnetic field is unaffected by Cross sectional area of the conductor.

Magnetic force: When a current-carrying wire is put in a magnetic field, the magnetic field exerts a force on the wire. The magnetic force is the name given to this force. The force exerted on a current-carrying wire is given by:

$F = I \bar{l} \times B$ It is the result of the length vector and the magnetic field being multiplied together.

Where I denotes current in the wire, l denotes wire length, and B denotes a magnetic field or magnetic flux density.

The force on the current-carrying wire is the product of the length vector and the magnetic field vector, also known as magnetic flux density (B).

The force on a current-carrying conductor is independent of the conductor's cross-sectional area, according to the force formula.

It is also affected by the current (I) passing through the conductor.

Fleming's left-hand rule determines the direction of the force.

According to Fleming's left-hand rule, if the thumb, forefinger, and middle finger of the left hand are extended perpendicular to each other as shown in the image, and if the forefinger represents the magnetic field, the middle finger represents the current, and the thumb represents the force,
