Question

A loop is rotating about y-axis in a magnetic field

b...... the voltage induced in the loop is

Answer 1

Use Biot-Savart law to derive the expression for the magnetic field on the axis of a current carrying circular loop of radius R. Draw the magnetic field lines due to a convection

Answer 2

Answer:

The open-loop gain of an amplifier is the gain obtained when no overall feedback is used in the circuit. Open loop gain, in some amplifiers, can be exceedingly high. An ideal operational amplifier has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around
