A wire segment carrying a current I is bent into a cosine shape with period of 2π, i.e., y=cos(x) and the wire has length 4π in the x−direction. There is a magnetic field in the vicinity of the wire which points in the positive z−direction with a magnitude given by B=B0x. What is the magnitude of the y−component of the force on the wire segment?

A positively charged particle of mass 6.82 x 10-8 kg is traveling due east with a speed of 64.2 m/s and enters a 0.397-T uniform magnetic field. The particle moves through one-quarter of a circle in a time of 4.06 × 10-³ s, at which time it leaves the field heading due south. All during the motion the particle moves perpendicular to the magnetic field. (a) What is the magnitude of the magnetic force acting on the particle? (b) Determine the magnitude of its charge. (a) Number (b) Number pi i Units Units V < B (out of screen)

A cylindrical bar magnet of radius 1.00 cm and length 10.0 cm has a magnetic dipole moment of magnitude m = 2.00 A · m2. What is the magnetization M, assuming it to be uniform in the magnet? Answer in x10^4(A/m)

The magnetic field inside an instrument is(B→=( 2.3 i^i^ - 1.4 j^)Tj^)T where B→ represents the magnetic field vector and TT stands for tesla, the unit of the magnetic field. a) What is the magnitude of the magnetic field? b) What is the direction of the magnetic field?
