If the induced cument in the loop is directed counterclock wise, is the magnetic field in the loop increasing or decreasing? Explain XxXxXXX XXXXx Xxxx)x 10. If three different resistors are connected in series, which resistor will have the largest voltage and which one will have the largest current? 7 Explain. 11. If a charge is moving perpendicular to a uniform magnetic field, what is the trajectory of the motion? Explain

Explanation / Answer

1. The induced current is in counterclockwise direction, hence the magnetic field is increasing. It can be found using the right hand thumb rule.

2. In series, the current in the circuit remains same.

And V = IR

So the resistor having maximum resistance will have maximum voltage across it.

3. F = q(v x B)

since v is perpendicular to B

So F = 0

Hence magnetic force does no work on the charged particle, it only changes the direction of the charged particle.

So the particle follows helical path in the direction of v
