Equation Sheet for Exam 3 Magnetic forces ● The Lorentz force is F = q v × B. The direction is determined by the right-hand rule. ● Combined electric and magnetic forces, F = q E + q v × B. ● The magnetic force on a current carrying wire is F = I × B L. ● The cyclotron equation. For a charged particle moving on a circle in a uniform magnetic field, qvB r mv = 2 Ampere’s Law ● The magnetic field due to a long straight current carrying wire is r I B π μ 2 0= . ● The magnetic field in a solenoid is L NI B 0 μ= . ● The magnetic constant is Tm/A 70 104 −×= πμ . Faraday’s Law ● Faraday’s law of electromagnetic induction: tΔ ΔΦ−=ε , where ε = electromotive force around a loop, and Φ = the magnetic flux through any surface bounded by the loop; Φ = B Aperp =B A cos θ . ● Transformer equations 2211 1 1 2 2 and VIVI N V N V == Light ● Snell’s law : 2211 θθ sinsin nn = . ● The index of refraction is n = c/v ● c = 2.998 × 108 m/s ● λ f = c ● 24 r P I π = Other information ● proton mass = 1.67 × 10−27 kg ● proton charge = e = 1.60 × 10−19 C
