- Solenoids are essentially coils of cord. These generate a magnetic subject which strives a pressure over a steel element.A solenoid is a fundamental time period for a coil of cord that we use as an electromagnet.
- We additionally consult with the tool which could convert electric power into mechanical power as a solenoid.
- Actually it generates a magnetic subject for developing linear movement from the electrical cutting-edge. With using a magnetic subject.
- Magnetic field at the centre of a solenoid of length 'L' having 'N' number of turns with a current 'I' is given by
...(1)
It is given that 1000 turns uniformly distributed over a length of 0.400 m produces a magnetic field of magnitude 1.00 ×10⁻⁴T .
Putting above values in equation (1) , we get

Answer:
B = 0.15 T
Explanation:
To find the magnitude of the magnetic field you use the following formula:
( 1 )
m: mass of the electron = 9.1*10^-31 kg
v: velocity of the electron = 3*10^6 m/s
q: charge = 1.6*10^-19
r: radius = 0.11mm = 0.11*10^-3 m
You replace the values of the parameters in the equation (1).
the magnetic field has a magnitude of 0.15 T
