1)A beam of electrona travels along an evacuated tube towards a floriscent screen.A coil is placed around the tube producing magnetic field along the axis of the tube. a)describe and explain the motion of the beam if: 1)it is exactly parallel to the axis of the tube My working: I think...

how do you find the direction of the magnetic force on a current loop..a loop that experiences a torque? i know you use some kind of right hand rule but I am confused also..the direction of a charged particle in a magnetic field please helpppppp

Magnetism: Magnetic field between wires Two long parallel wires are a distance of d = 1 cm apart and carry equal antiparallel currents of 8 Amperes. Find the magnetic field intensity (in T) at the point P which is equidistant from the wires. (R = 10 cm). This should be easy but I haven't...

magnetic forces on a conductor A straight, vertical wire carries a current of 1.13A downward in a region between the poles of a large superconducting electromagnet, where the magnetic field has a magnitude of 0.553T and is horizontal. What is the magnitude of the magnetic force on a section...

ok here's my problem(s)... I think the first one I'm missing something... it says: A particle initially moving south in a vertically downward magnetic field is deflected toward the east. What is the sign of the charge on the particle? Explain your answer with a diagram. So the way I...

here is the problem: prove that the vector of the magnetic force cannot be parallel to the plane that contains the vector of the particle's velocity and magnetic field. someone please help me to solve this, thanks so much for your time.

ok I'm stuck here... At a particular point in time, an electron is moving with a velocity of v=(2.0*10^6 m/s)i + (3.0*10^6 m/s)j in a constant magnetic field with strength e=(0.030T)i - (0.15T)j What is the magnitude of the magnetic force on the electron at that moment? this i found...

Find I2 so that the magnetic force per unit length on each wire is zero. The three parallel wires are equally spaced. Current directions are shown with '<' or '>'. I1 = I3 = 1 A < I1 < I1 < I1 --------------- > I2 > I2 > I2 --------------- < I3 < I3 < I3 --------------- I have...

Magnetism and magnetic force are typically explained by the resultant effect on moving charges. Is anyone aware of any reseach, studies or literature that quantifies the interactive forces between two or more magnetic objects without utilizing the effect on moving charges to explain interactive...

A Fe+ ion is traveling at 200 m/sec in a direction 20 deg south of west at a point. The magnetic field at that point is 0.4 T directed at 10 deg west of south. What is the instantaneous magnetic force that acts on the Fe is how many Newtons?

it is often said that "magnetic forces can do no work".. but a straight wire segment placed in a magnetic field experiences a force of mag. B*I*L (LaPlace' law) which accelerates it and thus does work.. how can this be true?? is it really an electric force that is doing the work here or what?

A segment of wire carries a current of 30 A along the x-axis from x=-6m to x=0 and then along the z axis from z=0 to z=5.5m. In this region of space, the magnetic field is equal to 14mT in the positive z direction. What is the magnitude F of the force on the segment of wire? Answer in units of...

Three parallel wires each carry current I in the direction shown in the figure (file attached). If the separation between adjacent wires is d, calculate the magnitude and direction of the net magnetic force per unit length on each wire. a) What is the magnetic force on the top wire? I think...

I'm stuck on this problem. I think it's the 3D geometry that's giving me the biggest problem. The current i exists in the direction shown (from left to right) in a parabolic wire segment whose equation is y = (x^2)/b in the XY plane between x = -a and x = +a. Magnetic flux density, given by...

I got sucked into the page on a website about magnets. It got into stuff about magnetic force on a moving charge. It said that the force on the charge is perpendicular to the magnetic field and the velocity of the charge. I got very confused because it called this force the "magnetic force" and...
