Question
Sketch the direction of B on the above diagram. Q5. LENZ'S LAW states that the induced EMF will try to produce a current WHOSE MAGNETIC FIELD OPPOSES the CHANGE in magnetic flux. (G) What will be the effect of the induced EMF when you: (a) try to reduce a magnetic field? (b) keep a magnetic field constant? (c) try to increase a magnetic field? The diagram shows a cross-section through a coil of a wire situated in a magnetic field. If B is (ii) DECREASING ..?n magnitude with time, what will be the direction of the current produced by the induced EMF? 79Explanation / Answer
(a) According to lenz's law it will try to decrease the magnetic field
(b) direction of the current will be out of page.
