As current intensity increases, the strength of the magnetic field around both a current-carrying wire and solenoid decreases.

Step-by-step explanation:

The magnetic field around a wire is given by :


image .......(1)

Where

I is current

r is the distance from wire

The magnetic field around the solenoid is given by :


image .....(2)

Where

N is the no. of turns per unit length

From equation (1) and (2), it is clear that the strength of the magnetic field in both current-carrying wire and the solenoid is directly proportional to the current. So, as current intensity increases, the strength of the magnetic field around both a current-carrying wire and solenoid increases. The given statement is false.
