The brightness of the light depends on the speed of rotation of
the wheel.
Arus aruhan bergantung kepada kelajuan
The greater the speed of the magnet in the coil wire, the greater
magnitude of the induced current.
Semakin laju, semakin bertambah arus aruhan.
To identify the relationship between the speed of
the magnet and the magnitude of the induced
current
Untuk mengkaji hubungan antara laju magnet dan gegelung dan
arus aruhan.
Manipulated/dimanipulasi : height of magnet/
tinggi magnet, h
Responding / bergerak balas: induced current / arus
aruhan, I
Fixed/ Malar : : no. turns of coil/ bilangan lilitan gegelung
wires
Magnet bar, gegelung wayar kuprum bertebat, miliammeter, pembaris
meter, wayar penyambung
• The height of bar magnet is adjusted at h = 20 cm.
• The bar magnet is dropped into the coil wire. Take the
reading of miliammeter
• The steps are repeated for h= 30 cm, h = 40 cm, h = 50 cm and h =
60 cm
h / cm I / A
