- In the last lesson, Lorenz's Law was applied to a current I traveling along a length of wire L, described by the formula, F-ILBsin(theta) In this lesson, Lorenz's Law is applied to a point charge q moving at velocity v, described by the formula, F-quBsin(theta) See how the IL is replaced by qv? Their units are the same: IL has units of amps meter and qv has units of C meter/s (amps is C/s). When applying the three-finger right-hand rule (RHR), the index "pointer" finger used for the direction of current is also used for the direction of the charge's velocity. In each scenario below, use the RHR to determine the direction of force: a) A positive charge's velocity v is directed up in a magnetic field B directed to the left, like this v /\ < B [Select] b) A positive charge's velocity v is directed down in a magnetic field B directed out of the page, like this v \/ o B [Select]An electric bus operates by drawing current from two parallel overhead cables, at a potential difference of 600 VV, and spaced 54 cm apart.

- Physics (Please, you can show all the steps explaining how to solve this problem. I do not fully understand this topic and I want to understand the procedure)A coaxial cable carries a current "I = 2 A". The inner conductor is a thin wire of radius "ρ = A = 0.5 cm" and the outer one has radius ρ = C =10 cm. It has a length h. between drivers there are two materials with permeabilities µ1 and µ2 as shown in the figure. (The purple area covers ¼ of the cylinder face and the orangezone ¾ ). Assume that the magnitude of the magnetic flux density inside the cable (both zones) is B = (1/ρ) in mT.a) Find (magnitude and direction) the magnetic field(s) H inside and outside the cableb) Make a diagram of the magnetic field lines inside and outside the wire.I don’t understand how they’re getting the formula of Vx(t) at the start by integrating could you show me how to resolve this in steps pleaseWhat is electrostatic shielding ? How does it work?
