Question

A square loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. The loop has total resistance of 0.8 ohms. It begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 T pointing into the page. Finally it leaves the field.

21)  While entering the field what is the direction of the induced current as seen from above the plane of the page?

clockwise

counterclockwise

zero

22)  While in the middle of the field what is the direction of the induced current as seen from above the plane of the page?

clockwise

counterclockwise

zero

23)  While leaving the field what is the direction of the induced current as seen from above the plane of the page?

clockwise

counterclockwise

zero

Answer 1

field is 21 &ince page gnetic field pointing into the 80 while entesting induced cursent will clockwise direction. hence m it middle 22) While will من در 0 in anticlockwise countes clockwise the field it will again 23) while leaving opposes direction hence the caure im clockwise CS Scanned with CamScanner
