Calculate the magnitude of the magnetic field 1 cm from the axis of a solenoid with radius 1.5 cm, 1000 turns per meter, and current I solenoid = 1 A, and from a long wire that runs through the middle of the solenoid with current Iwire = 100 A in the -2-direction. 3 sig figs, answer in units of mT, ~1 if nonzero
In a solenoid in vacuum of length l = 10 cm with 2052 turns per meter the current creates the field B = 70 µT. What will be the value of the current if the solenoid is placed in an external uniform magnetic field Bext = 35 µT with field lines exactly opposite to the field produced by the solenoid? Assume µo = 4Tt × 10¬7 H/m and give your answer in milli-amperes (mA).
The magnetic field B inside a long ideal solenoid is independent of what:( the current, the core material, the spacing of the windings, the cross-sectional area of the solenoid, the direction of the current.)
Can you help with subquestions 9a and 9b 9a. A very long solenoid with a circular cross section and radius r= 5.10 cm with n= 1.10E+4 turns/m has a magnetic energy density uB= 6.60 mJ/m3.

A current I is passed through a wire. A second wire of length L is moving perpendicular to the magnetic field generated by the first wire (see sketch below) with velocity v at a distance d. Write down the expression for the potential difference V between the ends of the moving wire. Consider the magnetic field B to be constant over the range of motion of the second wire (i.e. d » 1). Use μ for the vacuum permittivity. Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³), square root (sqrt(a*b/c) for √a× b/c) etc. For Greek letters use their names e.g. "theta", "alpha", "pi", "mu" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acose use A*cos theta. Please use the "Display response" button to check you entered the answer you expect. Wire 1 Wire 2 d V
A tightly-wound toroidal solenoid has a central radius (the radius midway between the inner and outer radii of the toroid) equal to R, a cross-sectional radius equal to b, N turns, and carries a current of I. In the limit as R approaches infinity, the magnetic field strength inside the toroid becomes: undefined equal to the magnetic field of an infinite solenoid with radius b equal to the magnetic field of an infinite solenoid with radius R zero
The figure shows a cross section of an infinite conducting sheet carrying a current per unit x-length of λ; the current emerges perpendicularly out of the page.
