Hint: F =Il´B. Bencircles the center counterclockwise. The current in a wireat r flows out of the page. Use the right-hand rule. A packed bundle of 100 long, straight, insulated wires forms acylinder of radius R=0.50 cm. Each of the 100 wires carries acurrent of 2.0 amps away from the page. What is the direction ofthe magnetic force on a wire a distance r=0.3cm from the center ofthe bundle? A)radially towards the center of thebundle B)radially away from the center if thebundle C)tangential to a circle with radius r=0.3cm,clockwise D)tangential to a circle with radius r=0.3cm,counterclockwise Hint: F =IlB. Bencircles the center counterclockwise. The current in a wireat r flows out of the page. Use the right-hand rule.

Explanation / Answer

A)radially towards the center of the bundle
B)radially away from the center if thebundle
C)tangential to a circle with radius r=0.3cm,clockwise
D)tangential to a circle with radius r=0.3cm,counterclockwise . Currents moving in the same direction always attract, so theforce of all these currents pulling on each other will be towardthe center of the bundle. . Incidentally, currents moving in opposite directions repeleach other.
