HELP PLEASE!!
How does the current (I) and the magnetic field (B) of the solenoid affect the frequency rotation of an electric motor??? So what is the relation between f Vs.I and of f versus B? Also, Establish a mathematical relationship between the frequency f and I and also between f and B.
Thank you!!

Pre-Lab for Experiment 03 A: A magnetic field in a solenoid is parallel to the axis of the solenoid. The current along the end of the teeter-totter is perpendicular to the magnetic field and therefore produced a force of F = 1, L,B, where 1, is the current in the teeter-totter and L, is the length of the conductor at the end of the teeter-totter. When well balance, weights on the other end of the teeter-totter produce a downward force...

Problem 5. (4 points) Electric field induced by a changing magnetic field in a solenoid. long solenoid of radius R = 10 cm has n = 100 turns/cm and carries a time-varying current that varies sinusoidally as I- Imax cos (2rft), where Imax- 10 A is the maximum current and f-60 Hz is the frequency of the alternating current source. What is the maximum magnitude of the induced electric field inside the solenoid, a distance r- 1.3 cm from its...

separately excited series, shunt, compound DC motor: *Describe how does decreasing the field current IF affect the speed versus voltage characteristic and constant K1 of a separately-excited dc motor. K1=(n2-n1)/(E2-E1) *Describe how does decreasing the field current IF affect the torque versus current characteristic and constant K2 of a separately-excited dc motor? k2=(T2-T1)/(I1-I2) *Briefly describe how the speed varies as the mechanical load applied to the series motor increases, i.e. as the motor torque increases.

How does seafloor spreading relate to magnetic reversals? The strength of the magnetic field will affect the width of the seafloor segment being produced. Parallel segments of seafloor form perpendicular to the direction of the magnetic field. Iron particles in cooling basalt align with the location of the current magnetic North Pole. There is no connection between seafloor spreading and magnetic reversals. Magnetic strength will affect the formation of submarine volcanoes. What role do mantle plumes play in mantle convection?...
