- Q2How can we increase the strength of the magnetic field of an electromagnet?add more copper wire to coilput more paper clips to pick upexpose to more lightclip on the alligator clips30sS5FE-IIIi-j-9
- Q3Which of the following serves as core of electric current in an electromagnet?batterycopper wirethumbtacksiron nail30sS5FE-IIIi-j-9
- Q4Which things at home would have an electromagnet?electric fansteel cabinetgas stoveironing stand30sS5FE-IIIi-j-9
- Q5Which material should we use to construct an electromagnet?Use yarn as wire.Use a silver spoon as coreUse abaca rope as wire.Use a black crayon as core.30sS5FE-IIIi-j-9
- Q6What flows through the conductor or copper wire in an electromagnet?static electricitylight wavesheat energyelectric current30sS5FE-IIIi-j-9
- Q7All of these help in strengthening the magnetic field of the electromagnet except one. Which one is it?adding more dry cells as sourcecoiling more copper wire to the coreusing chopsticks as iron coreplacing a bigger iron nail as core30sS5FE-IIIi-j-9
- Q8What is a force of attraction or repulsion of magnetic materials due to the management of atoms?MagnetismCircuitElectricityElectromagnet30sS5FE-IIIi-j-9
- Q9The relationship between the strength of an electromagnet and the number of coils is directly proportional. This means that -----As the number of coil increases, the strength of the electromagnet increasesAs the number of coil decreases, the strength of the electromagnet increases.As the number of coil increases, the strength of the electromagnet decreases.As the number of coil increases, the strength of the electromagnet is still the same.30sS5FE-IIIi-j-9
- Q10Which property of matter do we need in constructing an electromagnet?brittlenessflexibilityconductivityductility30sS5FE-IIIi-j-9
