3. A positively charged particle is travelling west and it encounters an extern field of unknown direction. The positively charged particle is then deflected due to the magnetic force exerted by the external field. Draw the situation to direction of the external magnetic field. 4. Two current-carrying loops are arranged so that one of the loops ju the other just like in the figure below. The current in each loop is dired counterclockwise. Draw the resulting magnetic field for each loop to d how the loops will "interact with each other. 5. A section of a current-carrying rectangular loop is placed inside a c carrying solenoid as shown in the figure below. Draw the magnetic fie by the solenoid to determine what will be its effect on the section of th loop inserted inside
