What is the magnitude of the force on the particle from the magnetic field?
The magnitude of the force is proportional to q, v, B, and the sine of the angle between v and B. If the particle velocity happens to be aligned parallel to the magnetic field, or is zero, the magnetic force will be zero.
What is the magnitude of the force experienced by an 8 Mev electron if it moves in the direction of a 5 Tesla magnetic field?
The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion. (Note that because the charge is negative, the force is opposite in direction to the prediction of the right-hand rule.) q v B = m v 2 r .
What is the strength of magnetic field known as?
Explanation: Strength of magnetic field is also known as magnetic flux density. It is the amount of magnetic field lines crossing unit area. 7.
How do you measure the strength of a magnetic field?
A current I through a long, straight wire produces a magnetic field with strength H=I/2πr at a distance r from the wire. So the field strength is inversely proportional to the distance from the wire.
How is magnetic strength calculated?
The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.
How do you calculate the magnetic field strength of an electromagnet?
To find the strength in gauss you must multiply the number of turns of wire in the electromagnet by the amperage.So for a example if you have a electromagnet with 20 turns of wire with 10 amps going through the wire then you multiply 20 by 10 and that will equals 200 so the magnetic feild it’s producing is 200 gauss.
What is the formula for magnetic field strength?
Magnetic Field Strength Formula and Derivation. First of all, the formula for magnetic field magnitude is: 4mu times 10^ {-7}T.frac {m} {A}) 4μ × 10−7T. Am. H and M would have the same units, amperes/meter. In order to further distinguish B from H, experts sometimes call the magnetic flux density or the magnetic induction.
How do you calculate the mass of a proton in picograms?
1 Answer. Stefan V. Mar 29, 2015. The mass of a proton in picograms is #1.67 * 10^(-12)”pg”#. This is a basic unit conversion problem in which you must go from one order of magnitude, in your case kilograms, to another order of magnitude, picograms. As you can see, 1 kg contains #10^(3)”g”#, and 1 g contains #10^(12)”pg”# .
What is the magnitude of the magnetic field?
So, the magnitude of the magnetic field is 6.00 T. Moreover, it can also be written as (micro-Tesla). Besides, the direction of the magnetic field can be determined using the ‘right-hand rule’ by pointing the thumb of your right hand in the direction of the current.
Why does a charged particle in a magnetic field have constant force?
Since their movement is always perpendicular to the force, magnetic forces due no work and the particle’s velocity stays constant. Since the force is F = qvB in a constant magnetic field, a charged particle feels a force of constant magnitude always directed perpendicular to its motion.
