A circular coil of 8 turns and a diameter of 30.0 cm is oriented in a vertical plane with its axisperpendicular to the horizontal component of the Earth's magneticfield. A horizontal compass placed at the center of the coil is made to deflect 45.0° from magnetic north by a current of 0.510 A in the coil.
a) What is the horizontal component of the Earth's magnetic field?b) The current in the coil is switched off. A "dip needle" is amagnetic compass mounted so that it can rotate in a verticalnorth-south plane. At this location, a dip needle makes an angle of18.0° from the vertical. What is thetotal magnitude of the Earth's magnetic field at this location?
An electric eel generates electric currents through its highly specialized Hunter's organ, in which thousands of disk-shaped cellscalled electrocytes are lined up in series, very much in the sameway batteries are lined up inside a flashlight.
A positive charge ball hangs, attached to a thread of negligiblemass. Similarly a negative charged ball hangs attached to athread of negligible mass. Each ball has mass of 0.14g and amagnitude charge of q. Attracted to each other, each of theirthr..
