Question 1 A satelite is in orit around the r Out there, he magnesc fild from te Earth is about 30 pT nd points in the not-south directon. The 5atelite ains a 1 sqare-meter wire loop It rotates around the axis the points away from the Earth. With what rotations rale (angular velocity) does the bop have to spin in order to produce a maximum af 10 V of EMF? There a bne that divides a region of zero magnetic held and a regon of Donstant, outward- poining magnatc fiold of 1 mT. A mota square loop of area 1 m by 1 m is initial compiatoly in the ero field regian is traveling at a apeed of 3 ms toward the nan-ero field region The loop has aresistance of 2 ato bald agian O- a. what is the arent in loop R9traverses line? b. Which direction is the arvamicw or CCW)? c Is the nduced current constant while the Ine is in the ? Question 3 A solanoid is powered by an increasing crent. This applied cumant in the solenoid is clockwise as ssen by you from the right. Nest to the solenoid is a metal ting (redl with the same radiu8 a8 the solenoid a. Whilb the cumant is increasing, what is the direction of the magnetic mamant at tho solenoid ltoward or away from you)? b. While the cument is increasing, weat is the drection of the magnate moment of th ring ltoward or away from you)? c. Are the solenoid and the ring attracted or repeled? Question 0m the top side A U-Shaped rnetal wie loop is angled above the for. Below aro two view8 Armetal bplaced on loop ard released from rest Find the speed at which the speed of the bar becomes constant. Use the resistance of the bar R 2Q, angle at the loop -20°, the width of te loop L " 10cm, ta mass of the bar is 10g. The applied magnesc feld is 0.1 T Question 5 A generator basically buit this way. There are coils attached the aade rat an outsite force il rotate. When rotsted, the coils mave from a north pole to a south pole and back and so on Lat's say esch eoil is 50 tums and each has an area of 1 em2 The strength of the magnet is constant with a field of 0.1 T. The axle is rotated at a rale of 10 rews. whthe maximum voltage that is generated at this rate?Explanation / Answer
1)Given,
B = 30 uT = 30 x 10^-6 T ; A = 1 m^2 ; e = 10 V
We know that induced emf when the coil rotates with angular frequency w is given by:
e = B A w sin(wt)
for maximum value of e, sin(wt) = 1
e = B A w
w = e/B A = 10/30 x 10^-6 x 1 = 3.33 x 10^5 rad/s
Hence, w = 3.33 x 10^5 rad/s
