Eksperimen Untuk menentukan kekuatan elektromagnet
Experiment
To determine the strength of an electromagnet

Mengkaji hubungan antara kekuatan Mengkaji hubungan antara kekuatan elektromagnet
elektromagnet dengan arus dengan bilangan lilitan solenoid
To investigate the relationship between the strength of To investigate the relationship between the strength of an
an electromagnet and the current electromagnet and the number of turns of the solenoid
Kekuatan elektromagnet bergantung kepada Kekuatan elektromagnet bergantung pada bilangan lilitan
Inferens magnitud arus elektrik. solenoid.
Inference The strength of an electromagnet depends on the The strength of an electromagnet depends on the number of
magnitude of the current. turns of solenoid.

Kekuatan elektromagnet (berdasarkan bilangan Kekuatan elektormagnet (berdasarkan bilangan paku yang
paku yang terlekat kepada elektromagnet) terlekat kepada elektromagnet) bertambah apabila bilangan

Hipotesis bertambah apabila arus elektrik bertambah. lilitan solenoid bertambah.
Hypothesis The strength of an electromagnet (indicated by the The strength of an electromagnet (indicated by the number
number of nails attached to the electromagnet) of the nails attached to the electromagnet) increases as the
increases as the current increases. number of turns of solenoid increases.
