Question
(a) Find the magnitude of the maximum magnetic force that could be exerted on the proton.
___N
(b) What is the magnitude of the maximum acceleration of the proton?
___m/s2
(c) Would the field exert the same magnetic force on an electron moving through the field with the same speed? (Assume that the electron is moving in the direction as the proton.)
Yes or No
Explain.
(d) Would the electron undergo the same acceleration?
Yes or No
Explain.
5.) A wire is formed into a circle having a diameter of 11.1 cm and is placed in a uniform magnetic field of 2.96 mT. The wire carries a current of 5.00 A. Find the maximum torque on the wire.
__ µN · m
6.) A rectangular loop consists of 110 closely wrapped turns and has dimensions 0.400 m by 0.300 m. The loop is hinged along the y-axis, and the plane of the coil makes an angle of 30.0° with the x-axis (see figure below).
What is the magnitude of the torque exerted on the loop by a uniform magnetic field of 0.816 T directed along the x-axis when the current in the windings has a value of 1.20 A in the direction shown?
___N · m
What is the expected direction of rotation of the loop?
-clockwise as viewed from above
-counterclockwise as viewed from the above
-The magnitude is zero.
(a) the speed of the electron
__m/s
(b) the radius of the circular path
___µm
9.) A cardiac pacemaker can be affected by a static magnetic field as small as 1.7 mT. How close can a pacemaker wearer come to a long, straight wire carrying 19 A?
___mm
10.) The two wires shown in the figure below are separated by d = 11.7 cm and carry currents of I = 4.55 A in opposite directions.
(a) Find the magnitude and direction of the net magnetic field at a point midway between the wires.
(b) Find the magnitude and direction of the net magnetic field at point P1, 11.7 cm to the right of the wire on the right.
(c) Find the magnitude and direction of the net magnetic field at point P2, 2d = 23.4 cm to the left of the wire on the left.

(a) Find the magnitude of the force per unit length that one wire exerts on the other.
___N/m
Explanation / Answer
1)
a) maximum magnetic force, Fmax = q*v*B*sin(90)
= 1.6*10^-19*6.2*10^6*1.47
= 1.458*10^-12 N
b) Apply, F = m*a
==> a = F/m
= 1.458*10^-12/(1.67*10^-27)
= 8.73*10^14 m/s^2
c) yes.
beacuse, electron and proton have same magnitude of charge.
But the direction of force on electron would opposite to the direction of force on proton.
d) No. beacuse electron has lower mass than proton.
