6.11 Electromagnet/ Keelektromagnetan
Inference / Inferens: The strength of the electromagnet depends on the current flow
Kekuatan elektromagnet bergantung kepada arus
Hypothesis / Hipotesis: When the current increases, the strength of the electromagnet increases.
Semakin bertambah arus, semakin bertambah kekuatan elektromagnet
Aim / Tujuan eksperimen: To investigate the relationship between strength of the electromagnet and current
Untuk mengkaji hubungan antara arus dan kekuatan elektromagnet
Variables/ Manipulated/dimanipulasi : current/ arus, I
Pembolehubah: Responding / bergerak balas: number of pins attracted/ bilangan pin, n
Fixed/ Malar : : number of turns of the coil/ bilangan lilitan
Apparatus / Radas dan Batteries, battery holder, rheostat, insulated copper wires, connecting wire, ammeter,
bahan: paper clips, nail, retort stand
Bateri, rheostat, wayar kuprum bertebat, wayar penyambung, ammeter, pin, teras besi
lembut, kaki retort

Arrangement of apparatus /
Susunan radas:

Procedure / Prosedur : • The switch is turned on.
• Adjust the rheostat so that the current, I = 0.1 A
• The number of paper clips that are attracted to the nail is counted
• Repeat the experiment with I= 0.2 A, 0.3 A, 0.4 A and 0.5 A

• Suis dihidupkan. Laraskan reostat sehingga arus 0.1 A.
• Hitung bilangan pin yang tertarik pada teras besi lembut.
• Ulang eksperimen dengan arus I = 0.2 A, 0.3 A, 0.4 A dan 0.5 A
