Question
In the figure below, a region with a constant magnetic field equal to 0.33 T into the page is shown. A single turn, rectangular loop of wire moves into this region with a speed of 16.3 m/S. The dimensions of the loop are a=0.66 m and b=0.4 m. The loop has a resistance of 2.95 . Xi- ty while the loop is moving into the region of constant magnetic field, the direction of the induced magnetic field in the loop is Submit Answer Tries 0/3 While the loop is moving into the region of constant magnetic field, the magnitude of the induced current flowing in the loop is Submit Answer Tries 0/20 Congtant magnetic Wld, the directior the magnetic orce acting constant magnetic field, the direction of the magnetic force acting on the loop is: Submit Answer Tries 0/3Explanation / Answer
1) As the is entered into the vertically downward magnetic field, according to Lenz's law, a magnetism will be induced in the coil such that the magnetic field will be coming out of the loop hence upper face of the loop will behave like North Pole.
2) motional emf induced across the length of the loop is given by
e = BvL = 0.33 × 16.3 × 0.66
= 3.55 Volt
Hence current induced i = e/R
i = 3.55/2.95
= 1.20Amp
3) according to Lenz's law, direction of magnetic force acting on the loop will be opposite to the direction of its motion.
