Question

Activity 3: The Moving Loop, Forces A rectangular loop has the following parameters: • • width w = 3 cm length 1 = 5 cm It is pulled at a uniform speed, v = 1.5 m/s, into, through, and out of, a uniform magnetic field of strength, B = 3.3 mt (into the page). v ♡ ♡ ♡ ♡ ♡ ♡ ♡ ♡ As the loop moves into, through, and out of the magnetic field, will the loop experience a net force and if so, when? If so, how would you find the magnitude and direction of the net force experienced by the loop?

Answer 1

Solution X X X X X X X X X X svi *4* xx x x x so x x x x x x Figure (9) A loop abcd enters a uniform magnetic field B at constant speed. Vo ubing Falooday is equatron. lela ) - par un chies) - L CBAX) – Be QX = BilV for the direction of current, we can use lenz's low As loop enters in magnetic field, the magnetic field pasting through the look moruases: Homee current in the look of anticlockwiseo For figure 6. there il no change in magnetic freed for the lool Honce in this care current in zero and in thin care lool (6) will not experience and force. And for figuu (C) magnetic flux through the loop is de cuared, so current in the look 98 clock wine ② Honce look abcd experlence . a force in the (a) and (6) camn only.

② Honce after finding the emfce=Bul) in the Circuit, find out Induced current pn od than. to cacciate the magnitude md directim. of Net farce experienced by the look are the Formula F = f Ind dex? F = Ind (IRE)
