1 If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. #(F//4)#.  If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value. #(4F)#.
Loop perpendicular to B-lines = 0Â¡ $ !B = AB 3) The angle  between B and normal to loop changes with t 12 Lenz's Law From conservation of energy: if current were opposite there would be a magnetic force on the magnet that increases v and this would increase the current in the loop and the force would increase...this is a diverging ef fect that violates energy conservation The induced current in a loop is in the direction that creates a magnetic field that opposes the change in magnetic flux through the area enclosed by the loop
