WebChanges in coil resistance also affect the coil temperature for DC relays. This is because a change in coil current causes the amount of power that is consumed to change. The value of temperature rise changes according to the rate of change in the coil current due to changes in the temperature. A typical example is shown in the following figure. WebMar 19, 2024 · 5.1: Relay Construction. An electric current through a conductor will produce a magnetic field at right angles to the direction of electron flow. If that conductor is wrapped into a coil shape, the magnetic field produced will be oriented along the length of the coil. The greater the current, the greater the strength of the magnetic field, all ...
