1- A solenoid with ( turn ) 1000 N connected with each side by galvanometer has resistance 4 Ohm , the solenoid was placed vertically inside a magnetic flux has 0.005 weber .

Calculate the average intensity of current induction that passing through the galvanometer if the magnetic flux increased to 0.0075 weber in 0.25 second knowing that the resistance of solenoid is 6 Ohm

2- A solenoid with ( Turn ) 100 N has placed vertically into a stable magnetic field has flux 0.002 weber , if the solenoid flipped in 0.2 second , find the EMF in the solenoid

Imagine you have a circular solenoid with N = 50 turns. The solenoid has a diameter of di = 1.5 cm, and the length of the coil is L = 35 cm. The coil is perpendicular to a uniform magnetic field of B = 0.75 T, and suddenly increases in diameter (remaining circular) from di = 1.5 cm to df = 3.0 cm over the course of 1 second. The coil has a resistance of 0.68 W. What are the...

The strength of the magnetic field within a solenoid is B = 2.1 × 10-2 T (outside the solenoid B = 0). A smaller, single loop is placed in the solenoid parallel to the plane of each loop in the solenoid. The resistance of the solenoid is 5.9 W, the resistance of the loop is 0.27 W, the diameter of the solenoid is 0.09 m, and the diameter of the loop is 0.05 m. An emf of 12 V is...

1) 2 point charges are separated by a distance of 8 cm. The left charge is 48 mC and the right charge is -16mC. Using a full sheet of paper: draw the 2 charges separated by 8cm, centered in the sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet length). [6] a) Draw field lines to indicate the electric fields for this distribution. [4] b) Draw 3 equipotential surfaces, 1 each, that pass: -Through the...
