The two grey circles represent plotting compasses placed near the ends of a solenoid. Electron flow current is running from the battery and through the coils. If you were to draw a needle on each of the compasses, which direction would they be pointing? *

The magnetic field at the center of a solenoid L = 75 cm long is B = 0.11 T when a current of I = 3.5 A flows through the solenoid wire. 1. Solve the formula for the magnetic field near the center of a long, tightly wound solenoid for the number of turns, N, in the solenoid. The expression should be in terms of the given variables. 2. Calculate the value of the number of turns, N.

A charge moves to the right and then enters a region with a uniform magnetic field as shown. If the charge follows along path 3 , what is the sign of the charge? The charge is positive The charge is negative The charge is neutral
You have learned that a charge moving in an magnetic field can experience a magnetic force. Remarkably, anytime that a charged particle moves that particle produces its own magnetic field! The image below of magnetic compasses forming a circle around a current-carrying wire demonstrates the shape of the magnetic field. The magnetic field lines forms concentric circles around that wire. The strength of the field decreases with increasing distance away from the wire. DOCES PAMIE DOCERE B If the current in the wire is 7.79A, what is the magnitude of the magnitude of the magnetic field (in μT, or micro-Tesla) a distance of 0.32m away from the wire? Note: It is understood that the unit of your answer is in μT, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.
can you help please. This is not and will not be graded
