Find the angle theta in degrees. g=9.8 m/s^2

Consider the following figure. 1 (a) A conducting loop in the shape of a square of edge length = 0.300 m carries a current I = 9.20 A as in the figure above. Calculate the magnitude and direction of the magnetic field at the center of the square. HT magnitude direction ---Select--- (b) If this conductor is reshaped to form a circular loop and carries the same current, what is the value of the magnetic field at the center? magnitude direction ---Select--- HT

Calculate the magnetic field strength (in T) needed on a 210 turn square loop 20.0 cm on a side to create a maximum torque of 300 N·m, if the loop is carrying 25.0 A.

A square loop,10.0cm on a side, is placed aroundthe center of a long solenoid which has 1500 turns of wire per meter. Thediameter of the solenoid is 9.00cm. The square coil has a resistance of 8.00. A cross section of the setup is shown toright. a.Determine the magnitude and the direction of the magnetic field inside the solenoid if it has a current of I=5.00 Amps in the direction shown. b.The initialcurrent through the solenoid is zero, at t =0 the current in the solenoid begins increasing according to the formulaI(t)=C1t2whereC1=5.00Amp/s2. Determine the magnitudeanddirectionof the current in the square coil at a time of .600 seconds.
