Question
I got the answers but don't know how to solve.
4. (a) Left
(b) Up
(c) into page
(d) out of page
(e) out of page
(f) left
(g) CW
(h) CCW
(toward top of page). down, left, right, into-the-page, out-of-page, or none. (a) A negative charge is moving downward (toward bottom of page) and a magnetic field is directed into the page. Find the direction of the force on this charge. (b) A wire has current moving to the left. A magnetic field is directed out of the page. Find the direction of the force on this wire. (c) A vertical wire has current moving downward. Find the direction of the magnetic field that this wire produces at point P (d) A loop of wire has current moving CCW. Find the direction of the magnetic field made by this current in the plane of the enclosed loop. (e) An electron is moving toward the left. Find the direction of the magnetic field that this electron produces at point P. (f) A loop of wire that has current moving CW is placed in a magnetic field that is directed downward. Find the direction of the torque on the loop.Explanation / Answer
here,
(a)
charge is moving downwards
charge is negative
the magnetic feild is into the page
using right hand rule
the force is towards right
(b)
current is towards left
magnetic feild out of the page
using the right hand rule
the force is upwards
(c)
current is downwards
using right hand thumb rule
the magnetic feild is into the page
(d)
as the current is CCW
using right hand thumb rule
the magnetic feild is out of the page
