An electron traveling due east in a region that contains only a magnetic field experiences a vertically downward force, toward the surface of the earth. A) What is the direction of the magnetic field? B) If it is a proton, what will be the direction of the magnetic field? Please explain the difference between electron and proton due to the current direction.
Question 4 (1 point) An electron traveling due east in a magnetic field in a lab experiences a vertically upwards force, away from the surface of the earth. What is the direction of the magnetic field? due north downwards, towards the earth upwards, away from the earth due south due east
At a certain location, Earth has a magnetic field of 0.60 x 10-4 T, pointing 75o below the horizontal in a north-south plane. A 11.0 m long straight wire carries a 15 A current. (a) If the current is directed horizontally toward the east, what are the magnitude and direction of the magnetic force on the wire? Magnitude Direction 75A" below the horizontal in the southward direction horizontal and directed due east 75A" above the horizontal in the northward direction...
A transmission line carries an 800-A current from east to west. The earth's magnetic field is 0.8 G due north but directed 60° below the horizontal. What is the force per meter on the line?
1. Assume the magnetic field is created by a pair of coils with a current circulating across them. If that current was increased by a factor of 2, how would the radius of the trajectory change? 2. Assume the electron is accelerated using an electric potential between two parallel plates. If that voltage was increased by a factor of 100, how would the radius of the trajectory change?
The size of the magnetic force on a straight wire of length
L carrying current I in a uniform magnetic field
with strength B is
F=ILBsin(?).
Here ? is the angle between the direction of the
current (along the wire) and the direction of the magnetic field.
Hence Bsin(?) refers to the component of the
magnetic field that is perpendicular to the wire, B?. Thus
this equation can also be written as
F=ILB?.
The direction of the magnetic force on...
What is the source of the Earth’s magnetic field in regard to dynamo theory, inner core, outer core, convection, and rotation? Who discovered the Earth’s magnetic field periodic reversals and How did they discover it? What is the current best theory of its cause? How does the magnetosphere interact with charged particles in the solar wind? What happens to a planet without a planetary magnetic field, like Mars?
the magnetic field west of the wire with current into the page is a)East b)west c)north d)south
A straight horizontal wire of length 5m is in a uniform magnetic field which has a magnetic flux density of 120mT. The wire is perpendicular to the field lines which act due North. When the wire conducts a current of 14A from East to West calculate the magnitude and direction of the force on the wire.
