(14)View more profiles with self-input
(15)That’s right.
(16)It’s the same thing to say, “Wrapping your nose tightly” and “Wrapping your spiral tightly
(17)The strength of the magnetic field is that the stronger the current in the coil, the closer the coil is, the stronger the magnetic field is
(18)The properties of magnetic fields are
(19)1 The closer the spacing of the lines of magnetic force, the stronger the magnetic field
(20)2 The direction in which the N pole of the compass needle points is the direction of the magnetic field
(21)3 If the direction of the current flowing through the coil is reversed, the direction of the magnetic field is also reversed
(22)a line of magnetic force continuously connecting the direction of a magnetic field
(23)We’re going to use this magnetic field to learn about electromagnetic induction
(24)Electromagnetic induction refers to the flow of electric current in a coil when a magnet is moved near the coil or when the coil is moved near the magnet
(25)It refers to the phenomenon And the current induced in the coil by this phenomenon is called the induced current
(26)The current induction process changes the magnetic field through the coil when the magnet or coil is moved, indicating that the change in magnetic field induces the current in the coil If you look at the picture above, you can see that the closer you get to the magnet, the tighter the lines of magnetic force, and the farther you go, the less that So when a magnet is close to the coil, the magnetic field passing through the coil increases, so the induced current increases, and the further away the magnet, the smaller the magnetic field passing through the coil, so the induced current weakens
(27)The above statement is that a change in magnetic field induces an electric current in the coil, and what happens if the magnet is stuck in the coil There is no change in the magnetic field at this time, so the current does not flow So the magnet has to move to induce the current This is how generators make electricity
(28)magnetic field in a coil
(29)Winding a wire is called a coil. A large magnetic field is generated when a wire is wound closely and an electric current flows through the coil. If an iron core is placed inside the coil, the iron core is magnetized when the current flows, increasing the strength of the electromagnet. If you wrap four fingers except your right thumb in the direction of the current flowing through the coil, the direction indicated by your right thumb becomes the N pole of the magnetic field
(30)the direction of the current
(31)the direction of a magnetic field
(32)Relationship between the direction of the current flowing through the coil and the direction of the magnetic field
(33)Comparing the strength of electromagnets with electromagnets with wires wound tightly
(34)If the wire is wound several times closely, the magnetic field of each loop is added to increase the overall magnetic field. Therefore, the closer the wire is wound several times, the stronger the electromagnet is

(48)201696-Slenod means a cylindrical wound electric coil For the coil, the solenoid is made by rolling a wire into a tightly cylindrical shape
(49)When you wind up and flow an electric current, you create a magnetic field inside the stomach and approach the magnetic material
(50)The strength of the flowing current increases
(51)Describe one way to make it big
(52)wind a coil tightly
(53)My first year of high school was the top student in my school
(54)The 20-point descriptive question has been processed to zero
(55)The question of whether to wrap the preface around the solenoid was
(56)The answer is “Wind a lot”
(57)”I wrote, “Wash it tightly”
(58)I’ve processed the earth science major, professor Koo Hak
(59)When I asked my friend who graduated from Seoul National University
(60)It’s close to getting closer together
(61)We raised an objection and science teachers will gather and have a meeting
(62)The teacher who scored it can only be partially tight even if it’s tight
(63)No, they say no
(64)I never thought this would actually happen
(65)First, I looked up the data
(66)When you describe the solenoid itself, it’s called “close.”
(67)For your information, I’ll upload the other files as well
(68)There were cases where the answer was “Wind closely” at other schools
(69)I think it’s used with a lot of things like thatThrough the homeroom teacher, the teachers explained what they meant
(70)There were a lot of cases
(71)I asked for my grades
(72)We’re going to set the conference solution
(73)I also worked with the president in charge of science
(74)”It’s my textbook.””I just wrote the answer and repeated the answer”
(75)I can’t do it, but I said I have a score for water
(76)The problem is that there are too many students in the middle school
(77)It’s difficult if it’s 2nd grade, and will it be 3rd or 4th grade
(78)I’m going to raise it’s high
(79)It’s already obvious that I made a resolution to apply for my grades
(80)Even if you reapply, it’s meaningless because the members decide
(81)I heard it’s better to sue around, so I’m going to court my friend fromYou’re gonna have to pay for a lawsuit. Period six is dog
(82)I’m 100% sure he’ll win
(83)I’m going to do it
(84)It’s about 00-700, and I’m a student lawyer
(85)You’ll get 1 result per month
(86)The cost of approximately 1 cost should be given to the winning side
(87)That’s it
(88)I have to go to school during the day on Wednesday
(89)I’ll meet the principal’s supervisor and science teachers together
(90)Can I explain to you the fee that’s on the top
(91)At first, it was Han’s judgment, and the first thing to do is to appeal to the vice president of the same science department, but it is not possible, but should we be gentle in complaining to the judge
(92)two ends
(93)Third
(94)That’s where I do it
(95)Is that so
(96)Lee Goeun, you’re washing up a lot
(97)I’m sure you’ll have to take a closer look at the same time
(98)Lee0 fortune teller
(99)I think they’re preparing a lawsuit
