PROBLEM

• What kinds of bulb are suitable for the headlight?

• How much voltage is needed to generate light?• How much voltage will pedaling produce?• What factors will affect the production of light?• How much speed will be needed in order to

generate light?

RESEARCH METHODOLOGYB. PROCEDURE• Collect the materials• Divide the magnet into 2 not-too-short pieces• Cut out the base or the whole container • Connect the magnets in the middle with a metal bar• Pierce the wooden base with metal bars ( nails were used instead and

make sure the shape is circular )• Wrap the copper wire around the• circle• Connect a wire to the copper wires inside

RESEARCH METHODOLOGY

B. PROCEDURE

• Pierce a hole on one of the sides and attach the light at the other side of the wire

• Place the magnets in the middle ( pre-attached to a gear )• Pierce the cover in order for the gear go through• Attach the gear to the moving parts of the bicycle• Attach the main magnet to the rope.• Measure the electricity produced using the ammeter. • Check the effectiveness of the light at a distance• Do finishing touches.

SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS

Summary on the Maximum Voltage (Volts) and Maximum Current (Amperes) produced by the Mechanical Electromagnetic Generator by pedaling

SACRED HEART SCHOOL – ATENEO DE CEBUSCIENCE INVESTIGATORY PROJECT PRESENTATION

SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS

Recommendations

• Make another generator that can produce more voltage.• Improve this generator so that it will be able to generate

enough energy to provide the headlight and taillight of a bicycle.

• Include a switch for the lights.• Find a way to store the unused energy when lights are

switched off.
