Below are the requirements for the Van De Graaff generator:

PVC Pipe 0.5″ X 2 ft
4 PVC Elbow
PVC pipe as lower roller 0.5″X4″
PVC pipe as upper roller 2″x4″ fixed roller
2 tee (PVC)
Teflon tape
AC/DC motor (100 rpm)
Metal sphere
Wire brush

The procedure for the Van De Graaff generator science project for class 10 is as follows:

Step 1: At the base, make a brush of thin copper wires from a thick electric wire.
Step 2: Set the brush beneath the roller and belt to eliminate negative charges.
Step 3: Connect the other terminal of this wire with a steel rod.

Note: This is done because negative charges have been produced at the lower end and positive charges at the upper end, so these negative charges have been drained out using the metal rod, or they can also be used for testing.

Step 4: Connect the lower roller to the shaft of the motor directly.
Step 5: Make a 2-inch wide belt out of the electric tape.
Step 6: Fix the 2-inch upper roller at the top. The reason for fixing this one is when the belt will move around, it will cause friction between the belt and roller resulting in the static charge being produced on it.
Step 7: Likewise, bottom one, make another wire brush by taking out copper wires from an electric wire. Set it above the belt to draw charges through the wire to be accumulated on the steel pot.

To prepare the Van De Graaff generator, one of the science projects for class 10th students, it must be remembered that the belt starts moving when the motor is turned on. It is due to the high friction on the top roller if it does not start moving, giving it a slight push.

Once it starts moving, it will rotate continuously. Ensure that there is no dirt on the roller as the generator might get stuck on the roller.

As soon as the generator starts, take a neon bulb and bring it closer. student's can observe a red glow. The intensity of light will vary depending on the distance of the bulb. By this method, student's can also find the point where the field intensity is the strongest. student's will notice that the charge has accumulated at the top.

Electromagnets are a type of magnet where an electric field produces a magnetic field. They consist of wire wound into a coil. Their magnetic property of attraction can be turned on or off as desired by switching off the flow of the electric current supply. Thus, unlike permanent magnets, the strength of the electromagnets can be altered by changing the amount of electric current that flows through them.

Electromagnets: Materials Required
Making of Electromagnets
Electromagnets Testing

Below are the requirements for the electromagnets project.

6V lantern battery
Enamel coated magnet wire, 30 AWG (75 feet)
Alligator clip leads-2
Iron bolts, 2.5 inches long and 0.5-inch diameter
220 grit sandpaper
Steel paper clips (more than 50)
Scissors/wire cutters
Paper towel holder or a pencil box

Making an electromagnet by wrapping a coil of wire around an iron core and determining the change in the electromagnet's strength with the number of coils wound.

Given below are step-by-step instructions to construct an electromagnet.

Step 1: Tightly wind the magnet wire around the iron bolts making four different electromagnets with 50, 100, 150, and 200 turns of wire, respectively.
Step 2: Use a paper towel holder or a pencil to hold the magnet wire spool while winding the magnets.
Step 3: Leave a tail of wire, minimum 6 cm long, at each end of the coil. Connect the coil to the battery using these wire tails.
Step 4: Use small pieces of masking tape to attach each end of the coil to the bolt to prevent it from unwinding.
Step 5: Unwind the magnet wire from the spool by rotating the iron bolt. Use the fingers to keep the wire tight against the bolt, and wrap each successive turn tightly against the previous one.
Step 6: The 50- and 100-turn coils should fit completely on the smooth part of the bolt. The 150 and 200 turn coils would go onto the threaded part.
Step 7: Keep track of how many turns you make.
Step 8: Use masking tape and a marker to label each magnet with the total number of turns.
Step 9: Use the 220-grit sandpaper for sanding off 1 cm of the enamel insulation from both ends of each coil.

The procedure to test the electromagnets are as follows:

Step 1: Make a data table like this.

Step 2: Put the paper clips in a small, shallow container.
Step 3: Starting with the 50-turn coil, use the electromagnets to pick up paper clips from the shallow container.
Step 4: The electromagnets would get hot if left connected to the battery in between tests.

Note: Always disconnect one alligator clip when the electromagnets are not in use.

Step 5: Connect one end of the red alligator clip to the positive terminal of the battery and the other end to one end of the wire coil. Make sure to connect to the part where the sanded off the insulation.
Step 6: Connect one end of the black alligator clip to the negative terminal of the battery, and the other end to the free end of the wire coil quickly to avoid heating of the electromagnet after it is turned on.
Step 7: Touch the bolt’s head to the pile of paper clips, and then pull the coil away from the tray.
Step 8: Some paper clips must attach to the bolt. If it does not lift any paper clips at all, then the electromagnet is not working.

Note: Move the bolt away from the tray, and then disconnect an alligator clip. This should turn the electromagnet off and the attached paper clips should fall away from the bolt.

Step 9: Count the number of paper clips that were attracted to the magnet, and note the value in the data table.
Step 10: Repeat step 3 four more times, for a total of five trials.
Step 11: Repeat steps 3–4 for the 100, 150, and 200-turn coils, and then disconnect the electromagnets from the battery.
Step 12: Calculate the average number of paper clips picked up for each number of turns in the coil.
Step 13: Make a graph of the results. Plot the number of paper clips picked up on the y-axis versus the number of turns in the coil on the x-axis.
