The astronomical object 4U014 + 61 has the distinction of creating the most powerful magnetic field ever observed.This object is referred to as a “magnetar” (a subclass of pulsars),and its magnetic field is 1.3 * 1015 times greater than the Earth’smagnetic field. (a) Suppose a 2.5-m straight wire carrying a currentof 1.1 A is placed in this magnetic field at an angle of 65° to the field lines. What force does this wire experience? (b) A field thisstrong can significantly change the behavior of an atom. To seethis, consider an electron moving with a speed of 2.2 * 106m>s.Compare the maximum magnetic force exerted on the electronto the electric force a proton exerts on an electron in a hydrogenatom. The radius of the hydrogen atom is 5.29 * 10-11 m
Figure is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, which is surrounded by an outer conductor, which is surrounded by another rubber layer. In a particular application, the current in the inner conductor I 2 is 6.00 A out of the page and the current in the outer conductor I 1 is 2.00 A into the page. Assume that l = 1.80 mm. Determine the magnitude and direction (upward or downward of the page) of the magnetic field at point b. (Choose upward of the page as the positive y-direction and express the magnetic field by using the sign of the result, which must be in µT and without decimals. That means if you get a result of a 922 and the direction of the field is upward of the page, just type 922 or if you find the direction of the field as downward of the page, just tpe -922 in the answer box. Maximum of 2% error is accepted in your answer. Take vacuum permeability µ 0 = 4π x 10 -7 T /A 2 and π = 3.14.)
