There is a current at I = 0.50 A flowing north in the wire. (The rest of the circuit, which actually delivers this current, is not shown.) The Earth's magnetic field at this location has a magnitude of 0.50 gauss (or, in SI units, 0.5 X 10'4 tesla) and points north and 38 degrees down from the horizontal, toward the ground. What is the size of the magnetic force on the wire due to the Earth's magnetic field? In considering the agreement of units, recall that 1 T : 1 N/(A . m).(EgLei) Express your answer in newtons to two significant figures. D View Available Hintts) X Incorrect: Try Again; 3 attempts remaining r Part B 'I The direction of the magnetic force is perpendicular to both the direction of the current flow and the direction of the magnetic field. Here is a "right-hand rule" to help you determine the direction of the magnetic force. (59%) 1. Straighten the fingers of your right hand and point them in the direction of the current. 2. Rotate your arm until you can bend your fingers to point in the direction of the magnetic field. 3. Your thumb now points in the direction of the magnetic force acting on the wire. N E D Part 0 ol > Part D Part A A rectangular 9.00 cm by 18.0 cm circuit carrying an 8.00 A current is oriented with its plane parallel to a uniform 0.770 T magnetic field (see the figure (Figure 1)).
