6. A current-carrying wire carries a current of 1.84 A. How far away from the wire is point P if the magnetic field at that location is 6.88 x 10 T? 0.747 A O 0.535 A 0.0535 A 0.0747 A4. A current-carrying wire carries a current of 1.20 A. What is the magnitude of the magnetic field at point P, 0.042 meters away from the wire? 7.00 x 10 8 T 7.00 x 10-9 T 5.71 x 10-5 T 5.71 x 106 T8. Which of the following is true about an electromagnet? Select all that apply. Increasing the current flowing through the wire makes a strong magnet. Decreasing the number of coils around the core makes a strong magnet. Adding more coils around the core makes a stronger magnet. Decreasing the current flowing through the wire makes a stronger magnet
