2. Electromagnet

Question 5

it is a metal or substance that can be a magnet in the presence of magnetic field

Answer 5

Ferromagnet

Question 6

the magnetic field is produced by electric current

Answer 6

Electromagnet

Question 7

physical phenomenon by the motion of electric charge

Answer 7

Magnetism

Question 8

it is the region around a magnet in which there is a force

Answer 8

Magnetic Field

Question 9

the ________ the two magnet is, the ________ the magnetism

Answer 9

closer, stronger

Question 10

magnetic line of force start from _____ pole to ______ pole

Answer 10

north pole to south pole

Question 11

the word ‘lodestone’ comes from the Anglo-Saxon word that means?

Answer 11

leading stone

Question 12

we use these lines to indicate the magnetic field

Answer 12

magnetic field lines

Question 13

when you bring two magnet together, what are the 2 possible field interaction that could happen?

Answer 13

it can be either attraction or repulsion

Question 14

what happens if the opposite pole of two magnets are brought close to each other?

Answer 14

the direction of the magnetic field aligns, causing attraction between the two magnets

Question 15

what happens if same poles of two magnets are brought close to each other?

Answer 15

the magnets will repel and the fields will create a neutral point where no magnetic field is felt

Question 16

they are produced by positive and negative charges

Answer 16

electric fields

Question 17

if a magnetic field points to the direction of the north pole, where does an electric field point to?

Answer 17

direction of a positive charge

Question 18

inside a magnet, the field runs from the _____ pole to the _____ pole

Answer 18

south pole to the north pole

Question 19

electric field lines have _______ starting and ending points

Answer 19

definite

Question 20

he is a Danish science who accidentally discovered electromagnetism

Answer 20

Hans Christian Oersted

Question 21

the direction of force can be demonstrated by using this rule

Answer 21

right-hand rule

Question 22

you can increase the strength of the magnetic field by?

Answer 22

increasing the flow of current

Question 23

coils or current-carrying wires that produce a magnetic field

Answer 23

solenoids
