A square rigid metal frame PQRS, of side 12 cm, forms a closed circuit with an ammeter. It is moved through an enclosed region of uniform magnetic field of flux density 2.0 × 10–2 T, from left to right. The field is confined to this area and directed into the page.
PQRS --> magnetic field -->
Give the direction of the current through the ammeter when enterting, in the middle, and leaving:
1. entering: anti clockwise
2. middle: no current (not cutting any lines of flux)
3. leaving: clockwise
How do we determine the direction of the current? I cannot do this using Flemings Left Hand rule?
