An electron in a TV CRT moves with a speed at 6.00107m/s, in a direction perpendicular to the Earth’s field, which has a strength of 5.00105T. (a) What strength electric field must be applied perpendicular to the Earth’s field to make the election moves in a straight line? (b) If this is done between plates separated by 1.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.)
Measurements at the weak and ?uctuating magnetic fields associated with brain activity are called magnetoencephalograms (MEGS). Do the brain’s magnetic fields imply coordinated or uncoordinated nerve impulses? Explain.
MagnetismDirections: Answer the following problem, write your answer with complete solution. If a 15C charged particle is traveling perpendicularly to a magnetic field of 8T at a speed of 2m/s, what is the force experienced by this charged particle?
Q2: In a cathode ray oscilloscope, 100 electrons are moving with a speed of 8.0 x106 m/s horizontally andpasses through the neck tube coils which creates a magnetic field of 25 mT. If It experiences a magneticforce of 2.8 X10-14 N, how can you predict the angle of motion of charges? If the charges are stationary,can the field produce magnetic force on these charges? If these charges are moving in an electric field, canit produce a force? Justify your answer for both cases.(Charge of electron=1.6 x 10-19 C.)
Using your basic understanding of magnetism and its laws, explain that, if a charged particle is not deflected in passing through a certain region of space, it does not necessarily mean that magnetic field does not exist in that region.
When charged particles from space are travelling parallel to the Earth’s magnetic field, what happens to them when they come into contact with the field? Use a diagram to support When charged particles from space are travelling perpendicular to the Earth’s magnetic field, what happens to them when they come into contact with the field? When charged particles from space are travelling at an angle between 0° and 90° to the Earth’s magnetic field, what happens to them when they come into contact with the field?
Q3. A proton has a mass of 1.67 x 10-27 kg, has a charge of 1.60 x 10-19 C, and moves is a circle of radius 21.0 cm perpendicular to a magnetic field of 4000G. Find (a) the speed of the proton and (b) the period of the motion.
Can't figure out how to even get the first part of this question, keep getting told my answer is wrong. Would love some help with each step of the way. An electron in a magnetic field moves along a circle with a radius of 26.5 m with a speed that follows: v(t) = v0e-bt where b = 0.46 s-1 and v0 = 143 m/s a.) What is the centripetal component of the acceleration at 4.8 s? b.) At 4.8 s, what is the angular acceleration? c.) What is the angular displacement for the electron from 0 s until 4.8 s? d.) What is the magnitue of the total accel. at 4.8 s?
How long would it take a 5" 8" human to grow 1cm if we turned off the electromagnetic force, holding them together? Answer: Approximately 84.0 million years.
Hi please help: a 0.32 μC particle moves with a speed of 18 m/s through a region where the magnetic field has a strength of 0.99 T. Express answers using two significant figures. a) at what angle to the field is the particle moving if the force exerted on it is 4.8 x 10^-6N? b) at what angle to the field is the particle moving if the force exerted on it is 3.0 x 10^-6N? c) at what angle to the field is the particle moving if the force exerted on it is 1.0x10^-7 N?
What is the magnetic force on a particle that has 0.000500 C of charge and is moving at 2.50 × 105 m/s to the right through a magnetic field that is 4.20 T and pointing away from you? Specify both magnitude and direction in your answer
what creates a magnetic field? how does this work in a magnet to create a strong magnetic field that ca attract or repel metals?
