Yes. Electricity flows from the negative side of a battery to the positive side. If you wrap your hand around the wire with the thumb following the electricity, the magnetic field will be moving in the same direction as the way your fingers are curled.
Hans Christian Oersted. In 1820, he discovered that an electric current could affect a compass needle.
Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.
Batteries and generators provide DC, Direct Current electricity.
AC electricity will not dissipate in charge traveling along a wire for up to hundreds of miles whereas DC dissapates at about 2 miles at its best. DC is simple and easy, the simplist electrical cirtuit possable.
by wires <<>> Electricity is not a collectible commodity. It is generated and distributed as the demand requires. Small amounts of DC electricity can be stored in a capacitor but is not viable as an AC source. Electricity is distributed by wire conductors.
Hans Christian Oersted. In 1820, he discovered that an electric current could affect a compass needle.
No, a traditional compass does not use electricity. It works based on the Earth's magnetic field to indicate directions.
same as DC electricity
In a DC circuit yes. The compass detects the magnetic field around the wire. Reverse the DC current and the compass will swing 180 degrees from the position is was in.
DC
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
DC: Direct Current
Yes, the compass needle will change direction if the flow of electricity in the wire near it is reversed. This is because the flow of electricity creates a magnetic field around the wire, which can interact with the magnetic field of the compass needle.
Humphrey Davy noticed that when he brought a wire with electricity running through it near a compass, the needle of the compass deflected, indicating that the electric current produced a magnetic field around the wire. This discovery led to the understanding of the relationship between electricity and magnetism.
You can put DC electricity through it
Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.
They provide DC power or current to run dc products.
