ACTIVITY B: PROBLEM SOLVING ON MAGNETIC FIELDS 1. Find the magnitude of the magnetic field of a wire carrying 5.00 A current 50.0 cm away. 2. The radius of a circular loop is 25.0 cm with long ends and carries a 2.00 A current. Find the magnetic field at the center of the loop. 3. Find the magnetic field created by wire carrying 3.00 A to another wire carrying 5.00 A and the distance between them is 20.0 cm. 4. Find the force between two parallel Wire carrying current 15.0 cm apart. The current in each wire is 4.00 A and the current is in the same direction
