Constants Suppose you go to Antarctic region (geographic south pole) for an undergraduate research project. Your location is very close to the magnetic pole of the earth. Assume that earth's magnetic field is uniform and has a strength of 60 ut. As a part of the experiment you hold a thin metal rod of length 20 cm and run toward east at a speed of 5 m/s. What direction should you hold the rod steady to get maximum emf in...

1) A 179‑turn circular coil of radius 3.55 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 13.7 Ω resistor to create a closed circuit. During a time interval of 0.121 s, the magnetic field strength decreases uniformly from 0.643 T to zero. Find the energy, in millijoules, that is dissipated in the resistor during this time interval. energy: mJ 2) You decide...

1) [7 marks] A long straight wire hangs vertically through the middle of a metal basketball hoop of radius R = 23.0 cm. The hoop is horizontal. The wire carries a current of I = 1.56 A, moving vertically upward from the ground toward the sky. a) Sketch the magnetic field inside the hoop, as viewed from above it. b) What is the magnitude of the magnetic field at the hoop's location? c) Is there a net magnetic flux through...

x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...
