Question 2 --/2 Our big lecture-table solenoid has 560 turns, each with 60 mm diameter, spaced tightly to only be 160 mm Long (left-to-right). The standard power-supply only needs 10.2 Volt to push 6.0 A current thru the solenoid wire, clockwise as seen from the right When turning off the power supply, we adjust the current to zero in 125 millisec. * read this * → [a) show that the magnetic field in the solenoid space used to be 0.02639...

A solenoid consists of 100 turns of a wire in a length of 0.200m. If the current in the wire is 3.00 A, what is the magnitude of the magnetic field along the axis of the solenoid? The solenoid has a cross-sectional area of 0.00200m2. If the current drops from 3.00 A to 0 in 1/60 s, what is the magnitude of the average induced emf in the solenoid?
A long solenoid consists of 1900 turns and has a length of 0.65 m. The current in the wire is 0.41 A. What is the magnitude of the magnetic field inside the solenoid? Submit Answer Tries 0/10 A small diameter, 61 cm long solenoid has 248 turns and is connected in series with a resistor and battery. The size of the magnetic field inside the solenoid is 2.424E-4 T when a voltage of 65.0 V is applied to the circuit....
A solenoid of length 20 cm and diameter 4 cm is constructed with 400 turns of wire The resistance of the wire can be neglected. A currenti is supplied to the solenoid in such a wav tha increases from zero to 0.5 A at a uniform rate over 2 seconds. Th 0.5 A. Calculate: e current then stays constant at (a) the inductance of the solenoid, (b) the maximum magnetic field in the solenoid, (c) the potential difference across the...
A solenoid is 3.0 cm long and has a radius of 0.50 cm. It is wrapped with 500 turns of wire carrying a current of 2.0 A. The magnetic field at the center of the solenoid is:
A thin (radius r=1.15 mm) long wire is used to build a solenoid: the wire is densely (subsequent turns touching each other) wound around a cylindrical surface of the diameter D=7.8 cm. When electric current I=1.5 A runs in this wire, what is the magnitude Bsol of the magnetic field in the center of the solenoid?: Bsol= ______ G. Let us now compare that magnetic field to the magnetic field B1 that would be produced just by a single circular...
