Question

A wire runs along the left edge of this page. If the free electrons in the wire arc going up the edge of the page, what is the direction of the magnetic field with respect to the middle of the page the field will go through point A from the left to the right across the page. the field will be directed into the page at point A. The field well go through point A from the bottom to top of the page. The field will be directed out of the page at point A. The field will be directed diagonally through point A from the upper left to lower right of the page. A bar of silver (black bar at the right in the drawing) is moving from right to left across the page. If there is magnetic field directed into the page. which side of the bar has a net negative charge? front back top bottom right left law expressed by the formula. epsilon =-N (Delta phi/Delta t)is used to determine the magnitude of the emf induced in a coil through which there is a changing magnetic flux? Ampere Faraday Lenz Maxwell Oersted Relative to the page what is the direction of live force on a negative charged particular moving down the page through a uniform magnetic field which is directed left to right across the page? right left up down into the page out of the page The torque on a single current-carrying loop is given by t- l AB sin theta. where theta is the angle between which quantities The current 1 and the B field. the plane the loop lies in and the B The normal to the plane the loop lies in and the B field. None of these.
