That's Benjamin Franklin, of course!
Answer:
Ørsted (Denmark) is generally credited with the discovery in 1821 that a magnetic field existed around all sides of a wire carrying an electric current which demonstrated that there was a direct relationship between electricity and magnetism. He (Ørsted) also observed that the effect was reciprocal:
- a current exerts a force on a magnet, and
- a magnetic field exerts a force on a current.
Ampère (France) followed up on this discovery in his examinantion of the impact of parallel wires carrying current

What are 3 essentials aspect of electric current?
An electric current has three 'effects'. These are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Any one of these effects can be used to define the unit of measurement for electric current, the ampere.Until around 1947, for example, the 'chemical effect' was used -i.e. the ampere was based on the mass of silver deposited on an electrode during electrolysis.Since then, the 'magnetic effect' has been used -i.e. the ampere is based on the force between two current-carrying conductors, due to their surrounding magnetic fields.
What is galvanometer magnetic force and motor effect?
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
What do the moving electrons in a wire produce?
An electric current produces a combination of three effects. These are the heating effect, the chemical effect, and the magnetic effect.The unit of measurement of current, the ampere(A), cold be defined in terms of any of these three effects. However, in SI, the ampere is defined in terms of its magnetic effect -i.e. the force of attraction or repulsion created by the magnetic fields surrounding two, parallel, current-carrying conductors. Prior to its present definition, current was defined in terms of its chemical effect -i.e. the amount of silver deposited by electrolysis over a given period of time.
What effect of current is utilised in bulb?
Heating effect of electric current.
What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
What do you mean by magnetic affect of electric?
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
History of magnetic effect of electric current?
i dont care i LOVE it
Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
What is magnetic effect of electric current?
A magnetic field is induced around any conductor carrying an electric current.As explained in the Oersted Theory.
What is the definition of the word electromagnetism?
Electromagnetism is the interaction of electric currents or fields and magnetic fields. It is the magnetic field created when an electric current passes through a wire, and is extremely useful because the magnetic effect stops as soon as the current stops.
What are the three effects of electric current?
Death, injury, and electricutionIf we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc.The SI unit of current, the ampere, is defined in terms of the force between two parallel conductors due to their magnetic fields (i.e. the magnetic effect).
What is an electrical properties?
If you are asking, 'What are the properties of an electric current?', then there arethree. They are (1) the magnetic effect, (2) the heating effect, and (3) thechemical effect. The unit of measurement of current, the ampere, is defined interms of the current's magnetic effect.If that's not your question, then this answer won't help you.WebRepcurrentVotenoRatingnoWeight
Why the flow of current is not visible in wire?
flow of electrons is not visible.only it can be sensedAnswerCurrent can only be detected through one or more of its effects. There are three effects of an electric current: heating effect, magnetic effect, and chemical effect. We use the magnetic effect (the force between currents in parallel conductors due to their magnetic effects) to define the ampere.

Why do magnets work?
Magnetic attraction occurs due to the effect of magnetic fields on electrical currents. An electric current would be the flow of electric charge (positive or negative depending on the amount of electrons present). A magnetic field is produced by moving electrical charges to effect other charges (basically).
What is a current in a circuit measured in?
ampsAnswerElectric current is measured by means of an ammeter. Electric current is expressed in amperes (symbol: A), which is defined in terms of the magnetic effect of an electric current -i.e. the force between two, parallel, current-carrying conductors.
