An electric current is uniformly distributed throughout a long, straight wire that has a diameter of 50 mm. The current through the wire is 5.0A . Calculate the magnitude of the magnetic field 20 mm radially away from the wire center. Calculate the magnitude of the magnetic field 50 mm radially away from the wire center. What must the current be to create a magnetic field of magnitude 1.0 T 50 mm radially away from the wire center?

You have been asked to design a magnetic trap for your summer internship. (a) First, consider a circular loop of wire of radius R located in the xz plane and carrying a steady current. Determine the magnetic field at an axial point P a distance x from the center of the loop. (Make sure to include a sketch.) (b) But, one loop isn’t going to get you enough B field strength, so you have to wrap 48 loops (8 layers...
