@ # Signin 07 el 66 @ o o CEED A Q) Force on a Current-Carrying Conductor 0 & 1. A 6.0 m wire carries a current of 7.0 A toward the +x direction. A mag- D netic force of 7.0 x 10~ N acts on the wire in the y direction. Find the magnitude and direction of the magnetic field producing the force. % 2. A wire 1.0 m long experiences a magnetic force of 0.50 N due to a per- pendicular uniform magnetic field. If the wire carries a current of 10.0 A, what is the magnitude of the magnetic field? 3. The magnetic force on a straight 0.15 m segment of wire carrying a cur- rent of 4.5 A is 1.0 N. What is the magnitude of the component of the r magnetic field that is perpendicular to the wire? 4. The magnetic force acting on a wire that is perpendicular to a 1.5 T uni- form magnetic field is 4.4 N. If the current in the wire is 5.0 A, what is the length of the wire that is inside the magnetic field?

Imagine standing at this location and facing north. Turn the palm of your right hand upward (the direction of the force) with your thumb pointing east (the direction of the veloc- ity). If your palm and thumb point in these directions, your fingers point direct- ly north in the direction of the magnetic field, as they should. PRACTICE A AN Pra Particle in a Magnetic Field 1 . 1. A proton moves perpendicularly to a magnetic field that has a magnitude 2. 3. of 4.20 x 10" T. What is the speed of the particle if the magnitude of the magnetic force on it is 2.40 x 10714 N? 2. If an electron in an electron beam experiences a downward force of 2.0 x 10 *N while traveling in a magnetic field of 8.3 x 10"- T west, what is the direction and magnitude of the velocity? 3. A uniform 1.5 T magnetic field points north. If an electron moves verti- cally downward (toward the ground) with a speed of 2.5 x 10' m/s through this field, what force (magnitude and direction) will act on it?
