Question
The magnetic field inside an infinite solenoid depends the distance r depends inversely on the distance r is constant. can't exist. Two protons are traveling in the directions shown. Draw the electric forces, F_E, on each proton due to the other proton. Draw the magnetic forces, F_B, on each proton due to the other proton. A positive ion is shot between the plates of a parallel plate capacitor hooked up to a battery as shown. To keep the ion moving ion a straight path between the plates a magnetic field should be directed into the page, pointing up. pointing down, out of the page. A current loop is placed between two bar magnets. Indicate possible motions the loop moves to the right, the loop moves to the left, the loop rotates clockwise, the loop rotates counter clockwise, the loop does not move. True False Amperes law is only valid in situations where you can argue the direction of the magnetic field from symmetry. True False The induced magnetic field is always directed to reduce the magnetic flux.Explanation / Answer
Magnetic field inside infinite solenoid is constant.
--------------------
electric force = alike charges repel.
magnetic force = q ( v x B)
and B due to proton = (u0 q / 4pi) ( v x r ) / |r|^3
direction of B = into the page for upper and out of page for lower proton.
Fb = upward for upper and downward for lower
-------------
electric force on charge will be downwards,
so magnetic field have to be upward.
and Fb = q ( v x B)
B will be into the page.
