We claim: 1. A gas turbine engine including a fluid flow control arrangement comprising: a supply of fluid; a conduit coupled to a component of the gas turbine engine, and the conduit coupled to the supply of fluid for supplying fluid from the supply of fluid to the component; a magnetic valve constructed and arranged to at least partially restrict the conduit in response to a temperature of a ferromagnetic material to control the flow of fluid through the conduit, the magnetic valve comprising a valve member, the valve member having at least a first configuration in which the conduit is at least partially restricted and a second configuration in which the conduit is relatively open; and at least one member and the valve member forming a magnetic circuit across the conduit, one of the valve member and the at least one member comprising the ferromagnetic material and the other comprising a permanent magnet or electromagnet, wherein the configuration of the valve member is controlled by magnetic flux in the magnetic circuit and is responsive to the temperature of the ferromagnetic material in the magnetic circuit. 2. A gas turbine engine including a fluid flow control arrangement, as claimed in claim 1, wherein the at least one member comprises the ferromagnetic material is thermally coupled to the fluid. 3. A gas turbine engine including a fluid flow control arrangement, as claimed in claim 1, wherein the at least one member comprises the ferromagnetic material is thermally coupled to the component. 4. A gas turbine engine including a fluid flow control arrangement, as claimed in claim 3, wherein the valve member is locatable in a non-rotating part of the gas turbine engine and the magnetic circuit includes at least a part locatable in a rotating part of the gas turbine engine. 5. A gas turbine engine including a fluid flow control arrangement, as claimed in claim 1, wherein the supply of fluid is compressed air or air. 6. A gas turbine engine including a fluid flow control arrangement, as claimed in claim 1, wherein the component is any one of: a turbine blade tip seal, a turbine blade or a nozzle guide vane. 7. A gas turbine engine including a fluid flow control arrangement, as claimed in claim 1, wherein the fluid is air. 8. A gas turbine engine comprising a component and a gas turbine engine fluid flow control arrangement, as claimed in claim 1, wherein the gas turbine engine fluid flow arrangement modulates the supply of cooling fluid to the component. 9. A magnetic valve for a gas turbine engine fluid flow control arrangement, as claimed in claim 1. 10. A method of controlling flow of fluid to a component of a gas turbine engine; the method comprising: providing fluid flow to the component of the gas turbine engine via a conduit; and partially restricting the conduit in response to a temperature of a ferromagnetic material using at least one member and a magnetic valve comprising a valve member, the valve member having at least a first configuration in which the conduit is at least partially restricted and a second configuration in which the conduit is relatively open, one of the valve member and the at least one member comprising the ferromagnetic material and the other comprising a permanent magnet or electromagnet, the valve member and the at least one member forming a magnetic circuit across the conduit, wherein configuration of the valve member is controlled by magnetic flux in the magnetic circuit and is responsive to the temperature of the ferromagnetic material in the magnetic circuit. 11. A method as claimed in claim 10, further comprising cooling the component by the fluid when the valve member is in at least the second configuration. 12. A method as claimed in claim 10, further comprising providing the fluid to a second component of the gas turbine engine when the valve member is in the first configuration. 13. A method as claimed in claim 12, wherein the second component is a combustor of the gas turbine engine. 14. A gas turbine engine including a fluid flow control arrangement comprising: a supply of fluid; a conduit coupled to a component of the gas turbine engine, the conduit coupled to the supply of fluid for supplying fluid from the supply of fluid to the component, and a recess in the conduit; a magnetic valve constructed and arranged to at least partially restrict the conduit in response to a temperature of a ferromagnetic material thereby controlling the flow of fluid through the conduit, the magnetic valve comprising a valve member movably disposed within the recess, the valve member having at least a first configuration in which the valve member is at least partially withdrawn from the recess to at least partially restrict the conduit and a second configuration in which the valve member is at least partially within the recess so that the conduit is relatively open; and at least one member and the valve member forming a magnetic circuit across the conduit, one of the valve member and the at least one member comprising the ferromagnetic material and the other comprising a permanent magnet or electromagnet, wherein the configuration of the valve member is controlled by magnetic flux in the magnetic circuit and is responsive to the temperature of the ferromagnetic material in the magnetic circuit.
