The magnitude of (induced) current depends on number of turns.
Arus aruhan bergantung kepada bilangan lilitan gegelung
When number of turns increases, the (magnitude of induced) current
increases
Semakin bertambah bilangan lilitan gegelung, semakin bertambah arus
aruhan.
To investigate the relationship between number of turns and (magnitude
of induced) current
Untuk mengkaji hubungan antara bilangan lilitan gegelung dan arus
aruhan.
Manipulated/dimanipulasi : Number of turns, N/ bilangan lilitan gegelung, N
Responding / bergerak balas: Current / arus aruhan, I
Fixed/ Malar : height of magnet/ ketinggian magnet
Magnet bar, gegelung wayar kuprum bertebat, miliammeter, pembaris meter,

• The insulated copper wire is wound around a cardboard tube with
number of turns, N = 20 turns.
• The height of a bar magnet from the above of top end of the solenoid,
H = 30.cm is measured
• The bar magnet is dropped into the solenoid.
• The reading of the ammeter (Current), I is measured.
• The experiment is repeated with number of turns, N = 40 turns, 60 turns,
80 turns and 100 turns.
