The principle is that different materials expand by different amounts when a given amount of heat is applied.
If two strips of metal are bonded together and heated then one will expand more than the other. Because they are bonded the only way this can happen is if the bonded pair curl and curve. So the metal on the outside of the curve covers more distance and is longer than the metal on the inside of the curve.
By arranging things correctly this property can be used to turn on and off an electrical circuit among other things.

What happens when you put a bimetallic strip in the flame of a burner?
When a bimetallic strip is exposed to the flame of a burner, the two metals in the strip expand at different rates due to their differing coefficients of thermal expansion. This causes the strip to bend as one side expands more than the other, demonstrating the principle behind the bimetallic strip's use in thermostats and temperature-regulating devices.
What is the Operating principle of a bimetallic strip?
A bimetallic strip consists of two different metals bonded together. When exposed to a change in temperature, the metals expand or contract at different rates, causing the strip to bend. This bending action is used in devices like thermostats to control temperature.
How much does a bimetallic strip cost?
The cost of a bimetallic strip can vary depending on the size, material, and manufacturer. On average, a bimetallic strip can range from a few dollars to tens of dollars.
How do bimetallic thermometer work?
Bimetallic thermometers work based on the principle that two different metals expand at different rates when heated. A bimetallic strip is made by bonding two different metals with different thermal expansion coefficients together. When the temperature changes, the strip bends due to the uneven expansion of the two metals, which is then measured to indicate the temperature.
What is a bimetallic strip and where can it be used?
A bimetallic strip is made of two different metals bonded together, which have different coefficients of thermal expansion. This causes the strip to bend when heated or cooled. Bimetallic strips are often used in thermostats, temperature switches, and circuit breakers to control temperature-sensitive mechanisms.

Can anyone explain the use of a bimetallic strip in heat regulation in an electric iron?
When the temperature of the iron increases, the bimetallic strip bends upwards. This breaks the contact between the strip and the heating coil. When the temperature falls, the bimetallic strip bends down and the contact is restored.

What is a bimetallic strip and What is it used for?
A bimetallic strip is a strip made of two different metals that have different coefficients of thermal expansion. When heated or cooled, the strip bends due to the difference in expansion rates between the two metals. This principle is used in devices such as thermostats to regulate temperature.
Which two metals are used in bimetallic strip?
Commonly, brass and steel are used in a bimetallic strip. This combination allows the strip to bend or warp when subjected to temperature changes due to the different thermal expansion coefficients of the two metals.
What is bimetallic strip made of?
A bimetallic strip is typically made of two different metals fused together, such as brass and steel or copper and iron. These metals have different coefficients of thermal expansion, causing the strip to bend when exposed to temperature changes.
