Answer 2

Answer:

The factors affecting the strength of a magnetic field in and around a current-carrying wire are:

1. The type of the metal of the wire
2. The amount of the current
3. The temperature of the wire

Explanation:

The strength of a magnetic field around a current carrying wire can be affected by the factors listed above because :

1. Type of metal that is used in current carrying wire also plays a major role in the magnetism of the magnetic field when placed close the wire.
2. The temperature of the wire will have a direct effect on the strength of the magnetic field.
3. The current flowing through the wire is directly proportional to the magnetic field , therefore an increase in the volume of current will result to an increase in the strength of the magnetic field, vice versa.  

Hence this explanation supports the statements that all apply on magnetic field of current carrying wire.
