Explanation:
The magnetic field around a wire is given by :
[tex]B=\dfrac{\mu_o I}{2\pi r}[/tex] .......(1)
Where
I is current
r is the distance from wire
The magnetic field around the solenoid is given by :
[tex]B=\mu_o NI[/tex] .....(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.
