Question

An electron moving upward from the bottom to the top of the page at 4.00 x 106 m/s travels through a magnetic field with a magnitude of 1.70 T. The electron experiences a magnetic force of 8.20 x 10-13 N.1. Find the angle between the electron and the magnetic field, and draw a diagram showing their interaction. Based on your diagram for question 1, In which direction will the electron be deflected? Draw a diagram showing the electron being deflected

Answer #1

An electron experiences a magnetic force of magnitude 4.60 x
10-15 N when moving at an angle of 60.0° with respect to
a magnetic field of magnitude 3.50 ´ 10-3 T. Indicate
respective directions of magnetic field vector and the force
vector. Find the velocity of the electron (its magnitude and
direction).

A beam of charged particles consisting of electron and protons
are moving in +x direction and enter a region of uniform magnetic
field in +y direction. If the protons are deflected in radius of
9.75ₓ10-2 m radius, calculate
a) The magnitude of the magnetic field
b) The radius that electron will be deflected and draw the
schematic of the problem.
c) The electric field that should be applied so that the protons
remain undeflected (both magnitude and direction)

An electron moving with a speed of 6.2×105 m/s in the positive x
direction experiences zero magnetic force. When it moves in the
positive y direction, it experiences a force of 3.9×10−13 N that
points in the positive z direction. What is the direction of the
magnetic field? What is the magnitude of the magnetic field?

An electron moving in the +x direction enters a magnetic field
that is directed toward the -z direction (into the plane of the
page). The direction of the force on the electron is ?

a uniform magnetic field is directed out of the page. electron
released with velocity initial from top to bottom of page. what is
the direction of the resulting force on the electron? possible
answers to left, to right, into page, out of page

An electron in a TV camera tube is moving at 5.80×106 m/s in a
magnetic field of strength 93 mT. Without knowing the direction of
the field, what can you say about the greatest and least magnitude
of the force acting on the electron due to the field?
Maximum force? (in N)
Minimum force? (in N)
At one point the acceleration of the electron is 8.365×1016
m/s2. What is the angle between the electron velocity and the
magnetic field? (deg)...

1. if electron moving in the +x direction and a force in the -z
direction , what is the magnetic field direction?
2. a negative charge (electron) moves in the +z direction and no
magnetic force due to the magnetic field, then what is the
direction of magnetic field?
what is the dirction of magnetic field, if there is magnetic
force?

Consider an electron moving to the right with some velocity: o
----->
A) What magnetic field would deflect this electron towards the
top of the page? Explain logic.
B) Explain how you would use a bar magnet to deflect the
electron as described in A.
C) Redraw the electron on paper. On the diagram, show how you
would position a current-carrying loop of wire, relative to your
electron, such that the electron was deflected as described in part
A. Show...

1. An electron is moving through a magnetic field whose
magnitude is 8.99 × 10-4 T. The electron experiences only a
magnetic force and has an acceleration of magnitude 3.22 × 1014
m/s2. At a certain instant, it has a speed of 8.44 × 106 m/s.
Determine the angle (less than 90o) between the electron's velocity
and the magnetic field.
2.Suppose that an ion source in a mass spectrometer produces
doubly ionized gold ions (Au2+), each with a
mass of...
