H = ____is the expression for the magnetic field due to an infinite linear current-carrying conductor

Magnetic Field Strength (H) gives the quantitative measure of strongness or weakness of the magnetic field.

H = B/μo

Where

B = Magnetic Flux Density

μo = Vacuum Permeability

Magnetic field due to infinite Linear current-carrying conductor is

B = μoI/2πr

B/μo = I/2πr

H = (I/2πr)A/m

Find the frequency of rotor induced EMF of a 3-phase, 440V, 50 Hz induction motor has a slip of 10%

Given Data

Voltage = 440 V

Frequency = 50 Hz

Slip = 10% =0.1

Now,

Rotor frequency = slip × frequency

= 0.1 × 50 = 5 Hz
