A sort of "projectile launcher" is shown in (Figure 1). A large current moves in a closed loop composed of fixed rails, a power supply, and a very light, almost frictionless bar (pale green) touching the rails. A magnetic field is perpendicular to the plane of the circuit. If the bar has a length ℓ = 30 cm , a mass of 1.5 g , and is placed in a field of 1.5 T , what constant current flow is needed to accelerate the bar from rest to 20 m/s in a distance of 1.5 m ? What is the direction?

Let’s Check 11 In this activity, please write TRUE if the statement is true and write FALSE if the statement is false. This is to check your understanding of the concepts. _________1.The voltage will be induced in a stationary magnetic field. _________2.

The conducting loop shown is moving into the region between the magnetic poles shown.a. Is the induced current (viewed from above) clockwise or counterclockwise?b. Is there an attractive magnetic force that tends to pull the loop in, like a magnet pulls on a paper clip? Or do you need to push the loop in against a repulsive force?

Magnetic flux describes the magnetic field through a surface. The left picture shows a view of pink magnetic field lines emerging from the page through a loop. The picture on the right shows another loop tilted with respect to magnetic field lines going through it. To find magnetic flux, use the formula where is the magnetic flux, B is the magnetic field, A is the cross sectional area, and is the angle between the electric field lines and the normal (perpendicular) to the surface area A. The units for flux is Webers (Wb) which is equivalent to Teslam . Airport security checks use walk-through metal detectors that detect changes in magnetic field. If the walk through area has a width of 1.0 m and a height of 2.2 m and is pulsed with a magnetic field of 0.0004 Tesla, what is the flux assuming no angle is involved? Airports may also use handheld wand metal detectors, like the one shown above. They emit magnetic fields of about 0.000008 Tesla. When using these wands, how much…
The problem below explores the basic principles behind electric generators, which we will discuss in class in detail. A 505 turn circular loop coil with a diameter of 3.9cm is initially held perpendicular to the Earth's magnetic field. The coil is then rotated in 7.6ms by 90 degrees, so the plane of the coil is parallel to the magnetic field. The average emf induced in the coil is 7.2V. Find the value of the Earth's magnetic field (in T) inducing the current in the coil.As an approximation, assume that the magnetic flux in the coil changes at a constant rate between its maximum and minimum values. Note that (see the previous problem) the flux through the coil is 505 times larger than if it was made out of one wire loop.
