Steps for performing Experiment

  1. Step:- Firstly user will open the simulator and see the arrangement in which primary adjustment has been done already. Now user will start the start.
  2. Step:- Now user will understand the concept of circuit design as discussed in theory portions.
  3. Step:- User will turn ON switch and simulator will ready for use.
  4. Step:- Now user will click on the connect compass button and compass will connected.
  5. Step:- Number of turns of the coil: The user can select the number of turns of the coil using this slider of number of turns of coil.
  6. Step:- Reverse current: Enables the user to reverse the direction of current through the circuit.
  7. Step:- Using the slider Radius of the coil, the user can change the radius of the coil.
  8. Step:- The slider along with the compass box can be moved along the arm of the apparatus using the slider Compass box position. The user can vary the distance x of the compass box from the centre of the coil.
  9. Step:- Adjust Rheostat slider can be used to adjust the current throuh the circuit.
  10. Step:- Add Row to Table: Click the "Add Row" button below the table.
  11. Step:-Verify Calculations: A new row will be added to the table. Review the table to ensure the calculations based on your inputs are correct.
