No. A coiled wire can never become an electric bell without some more pieces
and parts. When you have those, however, assembled in the right way, it's true
that passing an electric current through the coiled wire will cause the bell to ring.
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
Increasing the intensity of light or using a shorter wavelength light source can cause an electric current to flow in a photoelectric effect experiment. The energy of the photons should be increased to overcome the work function of the metal surface, allowing electrons to be ejected and generate a current.
An electrical current will cause an electromagnet to energise.
A potentially lethal electric current is typically on the order of 100 milliamperes (mA) or higher. Currents as low as 10 mA can be dangerous if they pass through the heart. It's important to remember that even lower currents can cause harm depending on the specific circumstances.
Typically, an electric current creates a magnetic force. Also, magnetic domains aligned correctly and properly can cause a magnetic force.
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
Yes, when an electric current flows through a coil wired to an electric bell, it creates a magnetic field. This magnetic field causes the coil to move and strike a bell, producing a sound.
An electric current is movement of electrons, no matter the source or cause.

yes
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
When a cable is coiled up, it can create additional resistance due to increased inductance and potential skin effect, which can limit the flow of current. The coiling can also cause the magnetic fields around the wire to interact, leading to energy loss in the form of heat. Additionally, if the coiled configuration leads to tighter turns, it can increase the impedance in the circuit, resulting in lower current flow. Overall, these factors contribute to a reduction in current when the cable is not fully extended.
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
6 MilliAmps across the heart.
It causes a proportional increase in current.
When an electric current flows through a wire wrapped around an iron nail, a magnetic field is created. This magnetic field aligns the magnetic domains within the iron nail, causing it to become magnetized. Once the current stops, the magnetic field dissipates, and the nail loses its magnetism.
