A very large loop of metal wire with radius 1 meter is driven with a linearly increasing current at a rate of 200 amps/second. A very small metal wire loop with radius 5 centimeter is positioned a small distance away with its center on the same axis (the loops are coaxial). Th...
Many metals become superconductors (zero resistance, zero loss, zero heating) at low temperatures. If they are warmed above the critical tempareature, the superconductivity is lost. Also, if the metal experiences a magnetic field above a critical value, the superconductivity i...

An infinitely long wire carrying a current of 2 A is bent at a right angle as shown in the Figure. What is the magnetic field magnitude in Tesla a point P, 10 cm from the corner? 6.06810^6 T is wrong
wrong answer. is there another solution to it? please try again. thanks
can an Amperian loop ever have a non-zero value of its line integral with the magnetic field.
Can someone please tell me where to find this: What was the "Era of Good Feeling" In Germany? All I can find is in the U.S but I need Germany. Thanks
