A wire through which a current is flowing lies along the x-ais as shown. Connecting wires which are not shown the diagram connect the ends of the wire to batteries (which are also not shown). Electron current flows through the wire in the -x direction, as indicated in the diagram. To calculate the magnetic field at location A due to the current in the wire, we divide the wire into pieces, approximate each piece as a point charge moving in...
2. (1) An aircraft is flying directly over the North Magnetic pole with a velocity V. The aircraft is pictured below as it would be viewed from above. What is the direction of the induced emf (voltage) on the wing? is this from P to or Q to P2. Draw the + and at the P and Qsides and explain. f ..P.. (11) A conducting loop of wire is horizontal. A bar magnet is pushed toward the loop from below,...

For this station, you have two coils of wire (each with different numbers of loops), a magnet, some connecting wires, and a galvanometer. A galvanometer is an ammeter that measures very small currents (micro-amperes) and indicates the direction of that current. Understanding how the meter behaves is important here, because you’re going to use the meter to determine/measure current—including its direction. For this galvanometer, when (conventional) current enters the terminal on the right (as viewed when reading the dial), the...
In Explorations 1 and 2, we have been focusing on the direction of the force on a current- carrying wire. It is obtained by using a right hand rule. Make sure you understand the right hand rule and how to use it to determine the direction of the force on a current- carrying wire when the direction of the magnetic field and the current are known. The magnitude of the force on a current-carrying wire is given by F =...
A strong magnet is placed under a horizontal conducting ring of radius r that carries current I as shown in the figure below. The magnetic field B makes an angle θ with the vertical at the ring's location. (a) what is the magnitude of the resultant magnetic force on the ring? (Use any variable or symbol stated above along with the following as necessary: π) (b) What is the direction of the resultant magnetic force on the ring? to the...
Use the right-hand-rule, determine the direction of the magnetic force on a current carrying strip in the following diagram, where the magnetic field is parallel to the surface of this paper: The magnetic force on the current strip is directed: a. to the left b. to the right upward d. c. downward "into the paper" e. f. "out of the paper" Use the right-hand-rule, determine the direction of the magnetic force on a current carrying strip in the following diagram,...
