A 3.0 cm wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. The magnetic field inside the solenoid is given to be 0.27 T. What is the magnetic force on the wire?

Text Solution

Verified by Experts

Length of the wire `1=3cm=0.03m,, ` Current flowing in the wire `1-10A`
Magnetic field `B=0.27T`
Angle between the current and magnetic field,`theta=90^(@)` (Because magnetic field produced by a solenoid is along its axis and current carrying wire is kept perpendicular to the axis)
`F=B i l sin theta, =0.27xx10xx0.03sin 90^(@), =8.1xx10^(-2)N`
Hence, the magnetic force on the wire is `8.1xx10^(-2)N`. The direction of the force can be obtained from Fleming’s left hand rule
