Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

### Magnetic Force on a Current-Carrying Wire

A copper wire of length 25.0 cm is placed in a magnetic field of 0.36 T (tesla). If it has a mass of 11.0 g, what is the minimum current through the wire that would result in a magnetic force equal to its weight?

- Options:
- 12 A
- 0.48 A
- 1.2 A
- 0.75 A
- 3.3 A

This question involves the interaction between electricity and magnetism, specifically how a current-carrying wire experiences a force when placed in a magnetic field. The force can be calculated using the formula:

\[ F = BIL \]

Where:
- \( F \) is the magnetic force,
- \( B \) is the magnetic field strength,
- \( I \) is the current in the wire,
- \( L \) is the length of the wire.

For the wire's weight \( W \) to equal the magnetic force \( F \), we equate \( F \) to \( W = mg \) (where \( m \) is the mass and \( g \) is the acceleration due to gravity).

### Explanation of Options

- Calculate the force necessary to counteract the wire's weight using its given mass.
- Use the relationship \( F = BIL \) to solve for \( I \), and identify which of the provided options matches the calculated current.
