Question

if number of turns of coil is 200 and the current is 100 mA , then MMF is​

Answer 1

Explanation:

Number of turns in a coil, N = 200

Current, I = 100mA

Magnetomotive force, \sf F_mF

m

= NI

• \sf F_mF

m

= 200 × 100 × 10⁻⁶

• \sf F_mF

m

= 2 × 10⁻² A

Answer 2

Given:

• Number of turns of coil = 200 turns
• Current through the coil = 100 mA = 0.1 A

To Find:

• Total magnetomotive force(MMF).

Solution:

Magneticmotoforce(MMF) is defined as the total current flowing through the electric circuit due to the presence of an electromotive force that is required to drive the magnetic flux in a magnetic circuit. The force which sets up the magnetic flux in a magnetic circuit is called MMF.  

The formula to find the MMF is given by,

MMF = N×I → {equation 1}

Where "N" is the number of turns of the coil, and "I" is the current.

Substitute the values from the given data in equation 1. We get,

MMF = 200 ×0.1 { multiplying the values}

MMF = 20 A-T

∴ MMF = 20 A-T
